Epson LQ-590II

24-pin impact print head

584 characters per second

USB and parallel ports

Monochrome document printing

The Epson LQ-590II is a monochrome 24-pin dot matrix printer built around a combination of speed, familiar impact-printing output, and modern connection options. Its listed maximum speed of 584 characters per second makes it one of the faster Epson models in this comparison, while the 24-pin head should be the priority for buyers who place greater emphasis on text and form detail than on the lower cost associated with nine-pin designs.

Pros

• High stated print speed
• 24-pin print detail
• Both USB and parallel
• Suitable for multipart forms

Cons

• No serial port listed
• No copy count specified

Connectivity is straightforward and practical: the supplied listing identifies both USB and parallel interfaces. Parallel support is useful for older business systems and legacy workflows, while USB makes the printer more convenient for a modern computer. Because the product is explicitly monochrome, it is aimed at text, invoices, shipping paperwork, and other documents rather than color graphics, photographs, or marketing materials.

The trade-off is that the supplied specifications do not provide a duty-cycle figure, copy count, or paper thickness rating for this particular listing. Those details are important if the printer will handle continuous multipart forms or sustained high-volume batches. Buyers should therefore verify those requirements with the current manufacturer documentation and seller listing rather than assuming they match every other LQ-590II configuration.

This is a strong choice for offices, warehouses, and financial operations that want 24-pin clarity without giving up parallel connectivity. It is especially appealing where print batches are large and a 584-cps maximum speed is useful. For lighter users who only need a basic impact printer, or for specialized jobs requiring a stated multipart-copy specification, one of the more fully documented Oki models may be easier to evaluate.

Speed for High-Volume Forms

A maximum monochrome print speed of 584 cps makes the LQ-590II well suited to batches of invoices, manifests, and multipart forms. Actual output time will vary with print mode, content density, and host-system processing, but the high headline speed is valuable when downtime or queue backlog is a concern.

24-Pin Output and Connections

The 24-pin head provides a logical step up from nine-pin machines when fine character formation matters. USB and parallel connections offer flexibility for both current computers and established legacy installations, although a buyer should confirm the cable and driver requirements of the exact setup.

• Energy Star designation

Cons

• USB not explicitly listed
• Copy count not specified

We may earn a commission when you buy through this link, at no additional cost to you.

Serial support can be valuable when integrating with specialized equipment or older point-of-sale and transaction systems. Parallel support similarly offers compatibility with legacy computing arrangements. The important consideration is that USB is not explicitly identified in the supplied specifications, so buyers should not assume a USB connection is present without checking the exact package and seller information.

Compared with the standard LQ-590II, this NT listing offers a similar stated speed and pin count but highlights serial connectivity and Energy Star compliance. The information supplied does not specify duty cycle, multipart-copy capacity, or paper thickness, so those factors remain important open questions for users of continuous forms or multipart carbonless stock.

Choose the LQ-590II NT when legacy interfaces are a genuine advantage rather than merely optional. It is less compelling for a newly built system that expects USB as the primary route, but it may be an excellent match for a stable industrial or office installation. Confirm interface availability, driver support, and the media path before ordering.

Built for Established Systems

Parallel and serial interfaces are the defining advantages for offices and industrial installations that still rely on legacy connections. They can reduce the need for interface conversion, but only if the host computer and printer configuration genuinely support the selected port.

Energy-Conscious 24-Pin Printing

The Energy Star designation gives this listing a distinct efficiency angle, while the 24-pin head and 584-cps maximum speed support detailed, fast monochrome output. It is a balanced option for sustained text-document workloads where power efficiency matters.

We may earn a commission when you buy through this link, at no additional cost to you.

The Microline platform is associated with multipart forms, invoices, and other jobs that benefit from impact printing onto carbonless or interleaved sets. That makes this model relevant to warehouses, shipping departments, accounting offices, and medical or administrative operations. Its exact paper path, copy count, interface set, and maximum speed are not included in the supplied listing, however, so those details should be checked before purchase.

The main compromise is information depth. While the model name and dot matrix format are clear, the product data does not quantify print speed, print resolution, duty cycle, or supported connections. A buyer who needs a nine-pin printer for ordinary forms may find the Microline 320 Turbo family easier to understand by comparing it with the closely related listings that include more detailed specifications.

For buyers seeking a capable and well-regarded impact printer without focusing on a 24-pin head, this is a compelling option. It is best suited to users who value the Microline 320 Turbo platform and its document-printing purpose, while confirming the exact media and connectivity specifications before finalizing the order.

A Practical Microline Choice

The Microline 320 Turbo/N is aimed at users who need a recognized dot matrix platform for routine forms and transactional paperwork. Its rating suggests broad customer appeal, although ratings should be considered alongside workload, media, and interface requirements.

Verify the Exact Configuration

Because the supplied specifications are concise, buyers should confirm pin count, speed, ports, and multipart-copy capacity on the current listing. That diligence helps prevent selecting a configuration that is not quite right for an existing form-processing system.

We may earn a commission when you buy through this link, at no additional cost to you.

USB and parallel interfaces cover the most common needs for a modern computer and a legacy business system. A stated maximum duty cycle of 20,000 pages is also useful for volume planning. A nine-pin head is appropriate for forms, invoices, reports, and shipping documents where legible monochrome text is the main requirement, though it will not provide the same fine character formation expected from a 24-pin model.

The main limitation is that the listed configuration does not mention a serial port or multipart copy count. The closely related 320 Turbo listing with fuller details supports an original plus up to five interleaf or carbonless copies, but that capability should not be assumed for model 62411601 without checking the exact package. Buyers should also consider separate supplies and compatibility with their forms.

This printer is a sensible recommendation for a business seeking a fast nine-pin model with modern USB support and a substantial stated duty cycle. It works especially well for repetitive transactional printing. Users prioritizing very fine print, color, or a broader interface set should compare it with a 24-pin Epson or a more fully specified Microline configuration.

Fast Nine-Pin Workhorse

The 435-cps speed is a major advantage for queues of invoices, manifests, and multipart paperwork. Nine-pin technology remains practical when speed, durability, and legible text matter more than photographic detail or polished graphics.

Interfaces and Workload Capacity

USB and parallel ports provide useful installation flexibility, while the 20,000-page maximum duty cycle gives buyers a clearer workload target. Exact paper handling and copy requirements should still be checked against the forms used in the intended application.

We may earn a commission when you buy through this link, at no additional cost to you.

Its 240 by 216 dpi resolution and monochrome nine-pin design align with traditional impact-printer output rather than inkjet-quality graphics. USB and parallel connectivity support both contemporary and legacy systems, while the Energy Star designation adds an efficiency consideration. The combination is especially useful for shipping offices, warehouses, point-of-sale operations, and back-office teams that continuously produce invoices or transactional records.

Although the Microline 420 is a faster and higher-duty-cycle option, the supplied data does not specify its multipart-copy count, supported paper thickness, or serial connectivity. Those details may influence the decision when carbonless forms are thick or an older serial setup is required. As a result, it is not automatically the right choice for every Microline 320 user.

Overall, this is a strong recommendation for buyers who need a nine-pin printer with greater speed and workload capacity than the 320 Turbo. It is a particularly good fit for high-volume monochrome forms where the priority is throughput and sustained use rather than the finer output associated with 24-pin print heads.

Throughput for Busy Print Queues

At 570 characters per second, the Microline 420 offers a meaningful speed advantage over 435-cps 320 Turbo models. That can be valuable in offices where long batches of repetitive forms would otherwise create a visible queue.

Designed for Sustained Workloads

The 24,000-page duty cycle and 128 KB memory support a high-volume interpretation of the printer's capabilities. Shoppers should compare actual monthly and daily output with the stated limit, then allow for service access and consumable planning.

Those three interfaces make the printer adaptable to a wider range of business systems than a model offering only USB or USB plus parallel. It can serve a modern workstation, an older host, or a specialized equipment environment without forcing every deployment into the same connection method. The 64 KB memory, 240 by 216 dpi resolution, and monochrome impact output complete a practical package for forms and business records.

The trade-offs are inherent to the nine-pin platform and this particular 120-volt configuration. A nine-pin head is suited to legible forms and transaction records rather than especially fine text, while a 120-volt product may not be the correct choice for every region or facility. The listing also does not specify a multipart-copy count, so that detail requires confirmation.

For most buyers seeking a flexible Microline 320 Turbo configuration, this is the leading recommendation. It combines a strong rating, a proven speed class, a respectable duty cycle, and the broadest explicit interface set in the comparison. It is especially appropriate for mixed legacy and modern environments that need one dependable impact printer.

One Printer, Multiple Interfaces

Parallel, serial, and USB connections give this 320 Turbo configuration unusual deployment flexibility. The printer can fit into a modern workflow or an established industrial and transactional system, subject to host compatibility and suitable cables.

We may earn a commission when you buy through this link, at no additional cost to you.

The supplied specifications identify a parallel port, which can be useful in an established environment built around legacy computing equipment. Monochrome output aligns with invoices, accounting records, shipping documents, and other text-oriented forms. The 550-cps maximum speed is also competitive for a 24-pin unit and should help when processing long batches.

Its 3.7 rating is the lowest among the featured products, and the listing does not explicitly mention USB. Neither fact automatically makes the printer unsuitable, but together they warrant closer review of recent customer feedback, system compatibility, and included accessories. The duty cycle and multipart-copy capability are also not supplied, which matters for heavy continuous-form users.

The LQ-2090II is most compelling for a buyer who prioritizes 24-pin detail and energy efficiency within an established parallel-port setup. It may be less attractive for a modern installation that assumes USB, or for a buyer wanting a clearly stated high-duty-cycle specification. Checking the exact configuration before ordering is essential.

Finer Characters for Business Forms

The 24-pin print head should appeal to users who value more detailed monochrome text than a nine-pin mechanism offers. It is a sensible fit for forms with small print, dense fields, or formatting that benefits from finer character definition.

Efficiency and Existing Infrastructure

Energy Star designation gives power-conscious buyers a useful consideration, while the parallel interface supports legacy infrastructure. Newer users should confirm whether USB or another modern connection is available for the exact package being considered.

Zero-tear and auto-park technology are also included to support more controlled paper handling. The printer supports Epson, IBM, ANSI, and Oki emulations, while USB and IEEE parallel connectivity covers the main installation options.

A maximum paper thickness of 17 mil and a 20,000-page monthly duty cycle give buyers additional planning information. The trade-off is that a nine-pin head and draft-focused speed prioritize throughput and forms over the finer output of a 24-pin model. The supplied description also lists parallel rather than serial connectivity, which may matter in specialized legacy environments.

This is the best-specified choice for operations that depend on multipart copies and need confidence in paper handling. It is a strong fit for warehouses, accounting departments, shipping operations, and manufacturers using carbonless sets. For a one- or two-copy workflow, the extra copy capability may be unnecessary, but for high-volume forms it is highly relevant.

Six-Part Form Production

The ability to produce an original plus up to five interleaf or carbonless copies makes this Microline configuration especially useful for multipart business forms. The stated 17-mil maximum paper thickness provides a useful reference when selecting stock.

Controlled Continuous-Feed Handling

Buying Guide – How to Choose the Best Dot Matrix Computer Printers

The right dot matrix printer depends more on workload, media, and compatibility than on a single headline speed figure. These factors help distinguish a basic forms printer from a machine intended for sustained commercial output.

Nine-Pin or 24-Pin

Choose nine-pin for high-volume transactional work, and choose 24-pin when document detail is a higher priority. The difference is most visible in small fonts and tightly packed forms, not in the printer's ability to produce ordinary business text.

Print Speed

Prioritize speed when printers process long batches or operate as shared workhorses. For occasional forms, media handling and compatibility may matter more than the difference between several hundred characters per second.

Interfaces and Compatibility

USB is the simplest choice for a modern standalone computer. Parallel or serial is valuable in an established legacy environment, and broad interface support reduces deployment friction when systems differ.

Multipart Copy Capability

Choose a clearly documented multi-copy model for carbonless or interleaved forms. Do not assume that every impact printer in the same model family supports the same number of copies.

Duty Cycle and Workload

Compare daily and monthly output with the stated limit. A higher limit gives more room for peaks, while a long service interval and reliable media loading become especially important.

Paper Handling and Media

Accurate media compatibility improves reliability and reduces wasted forms. Check the complete paper path, not just whether the printer is described as supporting continuous paper.

Output Resolution and Detail

Use sample output from the exact printer when possible. Fine detail matters most on small type, while routine high-volume work often prioritizes speed and reliability.

Energy and Operating Requirements

Check voltage, room, noise tolerance, and access to consumables before installation. Energy labeling helps with power planning but does not replace a full site assessment.

How to Use and Care for Your Dot Matrix Computer Printers

Begin by confirming that the printer, host computer, interface cable, print driver, and paper path are compatible with the intended application. Install the appropriate Epson, Oki, ESC/P, PPDS, or other supported driver, then perform a short test page before processing a large job. Load the correct tractor or continuous-form media, align the perforations, set the top of form, and verify that every copy layer feeds at the same rate. Running a small test on the actual form stock can prevent alignment errors and wasted multipart sets.

Choose a print mode that balances speed with legibility. Draft modes are useful for routine internal records, while higher-quality modes can improve small-text clarity at the cost of additional time. For multipart forms, confirm that the printer is configured for the number of copies and that the forms do not exceed the documented thickness limit. Inspect the platen, paper guides, tractor, and ribbon path for obstructions, and never force a jam that could damage the mechanism.

Treat the printer as a maintained business device. Keep the cover closed while operating, keep the work area free of excess dust, and avoid placing the unit near heat sources or direct sunlight. Replace consumables according to the manufacturer's guidance, inspect the print head and ribbon path routinely, and have a qualified service provider address persistent streaking, unusual noise, inconsistent alignment, or declining print quality. Before long unattended runs, use a representative test batch and check the first and last pages for feed consistency.

Frequently Asked Questions

What is a dot matrix computer printer used for?

Dot matrix printers are impact printers designed for text-heavy business documents such as invoices, purchase orders, shipping manifests, warehouse forms, and multipart records. They can print onto continuous tractor-feed paper and may create several copies in one pass. Their durable, mechanical printing method is especially useful when a workflow depends on preprinted forms or carbonless copies rather than graphics.

Are 24-pin dot matrix printers better than nine-pin models?

A 24-pin model generally produces more detailed characters and is preferable for small type, dense forms, and polished monochrome documents. A nine-pin model is usually faster and more economical for routine transactional printing, especially invoices, reports, and labels. The better choice depends on the required print detail, volume, and media rather than on one specification alone.

Can dot matrix printers print multipart forms?

Yes, many dot matrix printers are designed to print multipart forms and carbonless copies. The detailed Oki Microline 320 Turbo listing supports an original plus up to five interleaf or carbonless copies, while another Microline 320 Turbo listing supports an original plus five copies. Copy limits vary by model, so check the specifications for the exact printer and confirm that the form thickness falls within its supported range.

Which connection should I choose for a dot matrix printer?

USB is the most convenient choice for a modern standalone computer, while parallel or serial can be necessary for established industrial or legacy systems. The Oki Microline 320 Turbo 91907101 provides USB, parallel, and serial connections, making it especially flexible. Consider the host system, available port, cable, driver, and print-server setup before purchasing.

Is print speed the only factor for high-volume printing?

No. Duty cycle, copy support, paper handling, interface options, media loading, consumable availability, and serviceability are all important. A fast printer with an inadequate duty cycle or incompatible forms may be less useful than a slightly slower model designed for sustained operation. Compare the actual workload with the manufacturer's limits.

Do dot matrix printers only work with continuous paper?

Dot matrix printers are strongly associated with continuous tractor-feed paper, but their exact supported media depends on the model and configuration. Some can also handle cut sheets or other compatible media through an appropriate paper path. Check the manual for supported widths, thickness, tractor position, and multipart capabilities before ordering.

What should I look for in dot matrix printer drivers?

The driver should support the printer's connection method, command language, operating system, paper configuration, and desired print mode. ESC/P and IBM PPDS are identified for the Epson LQ-590, while the detailed Oki Microline 320 Turbo listing supports Epson, IBM, ANSI, and Oki emulations. In a legacy environment, verify compatibility with the application and host system before installation.

How do I reduce paper jams in a dot matrix printer?

Use compatible media within the documented thickness limits, align the perforations correctly, and make sure tractor pins sit fully in their slots. Keep the path free of torn paper and debris, and use the printer's zero-tear, auto-park, or form-position controls when available. If jams persist, check ribbon placement, guides, platen condition, and the printer's paper settings rather than applying force.

Final Thoughts on Choosing the Best Dot Matrix Computer Printers

The Oki Microline 320 Turbo 91907101 is the strongest all-around recommendation because it combines a 5.0 rating, 435-cps output, a 20,000-page duty cycle, and USB, parallel, and serial connections. The Microline 620 stands out for premium high-volume positioning, reliable performance, and simplified media loading, while the Microline 320 Turbo/N offers a well-regarded, value-oriented entry into the Microline platform.

Before buying, prioritize the requirements that cannot be changed easily: media type, multipart-copy count, print quality, duty cycle, interface compatibility, and electrical setup. A nine-pin model is often enough for routine forms, while a 24-pin Epson may be warranted for dense or detailed documents. Buyers who need several copies should favor a configuration with clearly stated copy support, such as the detailed Microline 320 Turbo listing.

Retailer prices, product availability, ratings, and bundle contents can change, so compare the current listing with the manufacturer's documentation before purchasing. Confirm drivers, cables, consumables, accessories, warranty coverage, and return terms. Those final checks help ensure that the selected dot matrix printer fits both the documents being produced and the system in which it will operate.
