The Best Dot Matrix Computer Printers

Understanding Dot Matrix Technology

Dot matrix printers work by striking an ink-soaked ribbon against paper using a print head with pins. This impact method allows for carbon copies and is ideal for high-volume, continuous printing in business settings. They are generally slower than inkjet or laser printers but offer superior durability and lower running costs for certain applications.

Key Features to Consider

• Print Speed: Measured in characters per second (CPS), higher CPS means faster printing. Consider your typical print job volume.
• Resolution (DPI): While not as critical as for graphics, a higher DPI can offer slightly clearer text, especially for barcodes or logos.
• Number of Pins: Common configurations are 9-pin and 24-pin. 24-pin printers offer higher print quality and finer detail.
• Connectivity: Look for USB, parallel, or Ethernet ports depending on your existing computer setup and network requirements.
• Paper Handling: Check for support for continuous feed paper, cut sheets, and the ability to handle multi-part forms (carbonless or carbon copies).
• Durability (MTBF): Mean Time Between Failures (MTBF) indicates how long the printer is expected to operate without issues. Higher MTBF is better for heavy use.

Print Quality and Applications

For basic text documents and receipts, a 9-pin printer is usually sufficient. If you need to print detailed forms, invoices with logos, or high-resolution barcodes, a 24-pin model will provide superior clarity. These printers excel in areas like shipping, accounting, inventory management, and any industry requiring multi-part forms.

Maintenance and Running Costs

Dot matrix printers primarily require ribbon replacements, which are inexpensive and readily available. Ensure the printer's design allows for easy ribbon changes. Consider the cost and availability of replacement ribbons when making your decision. Regular cleaning of the print head and platen can extend the printer's lifespan.
