Epson LQ-2170 Driver, Windows Setup, Dot Matrix Not Printing, Continuous Paper, Tractor Feed, Tear-Off, Ribbon, and Alignment Problems

The Epson LQ-2170 is a 24-pin impact dot matrix printer used for multipart forms, continuous paper, invoices, shipping documents, reports, and older office or terminal-style printing. It uses tractor feed, paper-release lever positions, ribbon output, ESC/P2-style printing behavior, and Windows port/driver settings rather than the same workflow as inkjet or laser printers. 

Users most commonly faced Windows driver matching problems, parallel/USB-adapter setup failures, printer not printing from modern Windows, continuous paper not feeding, wrong top-of-form or tear-off position, faded ribbon output, paper jams, and jobs printing with the wrong font, spacing, or page length.

Problem: Epson LQ-2170 is connected through USB-to-parallel adapter but does not print

What users observed: Users connected the LQ-2170 to a modern computer through a USB-to-parallel adapter, but Windows did not print reliably. The printer could appear as USB printing support, an unknown printer, or a printer using the wrong port.

What was tried: Users changed USB ports, tried another adapter, checked Device Manager, changed the selected printer port, reinstalled the Epson driver, and tested a basic text print.

How this played out: The fix was port matching. Users installed the adapter path first, confirmed which USB virtual printer port Windows created, assigned the LQ-2170 driver to that port, cleared the queue, and printed a simple test page. Adapter-based setups became stable after the Windows port matched the adapter instead of an old LPT entry.

Problem: Epson LQ-2170 parallel port setup fails on older desktop

What users observed: Users connected the printer through a real parallel/LPT port, but Windows did not print. The printer could be powered on and ready, while jobs stayed in the queue or went to the wrong port.

What was tried: Users checked LPT1, changed BIOS parallel-port settings, selected the local printer port, reinstalled the driver, and tested printer self-test output.

How this played out: The repair path was local port validation. Users confirmed the printer self-test worked, selected the active LPT port in Windows, checked BIOS parallel-port state, and assigned the LQ-2170 driver to that port. Printing returned after the driver and hardware port pointed to the same connection.

Problem: Epson LQ-2170 appears offline in Windows

What users observed: Windows showed the LQ-2170 as offline even though the printer was powered on. Jobs stayed in the queue and did not move.

What was tried: Users checked the cable, restarted the printer, restarted Windows, disabled Use Printer Offline, checked the selected port, and removed/re-added the printer.

How this played out: The fix was offline-state cleanup. Users cleared Use Printer Offline, restarted the print spooler, checked the active LPT or USB virtual port, and rebuilt the printer entry. The queue returned to ready state after stale offline status and wrong-port selection were removed.

Problem: Epson LQ-2170 print queue gets stuck

What users observed: Users sent one or more jobs to the LQ-2170 and the queue stopped moving. One failed print job blocked later jobs, and canceling the document did not always clear the queue.

What was tried: Users canceled documents, restarted the printer, restarted Windows, restarted Print Spooler, removed the printer entry, and tested a small text file.

How this played out: The repair path was stuck-job removal. Users stopped the spooler, cleared stuck queue files, restarted the service, and sent one fresh text job. The queue started moving again after the failed print data and stale printer entry were cleared.

Problem: Epson LQ-2170 continuous paper does not feed correctly

What users observed: Users loaded tractor paper but the printer did not feed it correctly. Paper could fail to move, skew, jam, or feed from the wrong path. Epson’s LQ-2170 documentation emphasizes setting the paper-release lever for the selected paper type and feed path before printing.

What was tried: Users adjusted the paper-release lever, reloaded tractor paper, checked sprocket position, aligned holes on the tractor pins, reduced paper tension, and tested form feed.

How this played out: The fix was paper-path setup. Users set the paper-release lever to the correct continuous-paper position, aligned the tractor holes on both sprockets, locked the paper guides, and used form feed to confirm smooth movement. Continuous paper fed correctly after lever position and tractor alignment matched the loaded paper path.

Problem: Epson LQ-2170 single-sheet paper does not load

What users observed: Users tried to print single sheets, but the paper did not load properly or the printer stayed in a continuous-paper state. The printer expected the paper-release lever and source settings to match the paper type.

What was tried: Users moved the paper-release lever, reloaded single sheets, checked paper guides, changed paper source in the driver, and tested another sheet.

How this played out: The repair path was single-sheet source correction. Users moved the paper-release lever to the single-sheet position, aligned the sheet with the paper guide, selected the matching paper source in the driver, and printed a test page. Single-sheet loading became reliable after the physical lever and driver paper source matched.

Problem: Epson LQ-2170 prints compressed, stretched, or with wrong spacing

What users observed: Users saw text squeezed, stretched, shifted sideways, or printed with the wrong character spacing. Dot matrix output depends on CPI, font, printer emulation, driver settings, and application form layout.

What was tried: Users changed CPI, selected a different font, changed the printer driver, tested Generic/Text Only, adjusted margins, and printed a plain text sample.

How this played out: The fix was font and emulation cleanup. Users selected the correct Epson LQ driver or text driver for the application, matched CPI and page layout, cleared the queue, and printed a test form. Spacing returned to normal after the application and driver sent the expected dot matrix text format.

Problem: Epson LQ-2170 prints faded or very light

What users observed: Users printed documents that were too faint to read, especially on multipart forms. Since the LQ-2170 is an impact printer, light output usually points to ribbon, platen gap, printhead impact, or paper thickness rather than ink or toner.

What was tried: Users replaced or reseated the ribbon, adjusted the paper-thickness lever, checked multipart form thickness, tested a single sheet, and printed another sample.

How this played out: The repair path was ribbon and paper-thickness correction. Users installed a fresh ribbon, seated it properly, adjusted the paper-thickness lever for the loaded form, and tested output on plain paper. Print density improved after the ribbon and paper gap matched the media.

Problem: Epson LQ-2170 prints dark smudges or dirty marks

What users observed: Users saw smudges, dirty marks, or ribbon ink transfer on forms. The printer still printed, but the paper looked dirty or over-inked.

What was tried: Users checked ribbon seating, adjusted the paper-thickness lever, cleaned the paper path, checked multipart form thickness, and tested a new ribbon.

How this played out: The repair path was ribbon-path cleanup. Users reseated the ribbon, corrected paper thickness, cleaned accessible paper-path areas, and tested a fresh page. Smudging cleared after the ribbon and paper path stopped dragging against the sheet.

Problem: Epson LQ-2170 ribbon does not move or output fades quickly

What users observed: Users replaced the ribbon but output stayed faint or faded quickly across the page. The ribbon could be installed incorrectly, jammed, or not advancing.

What was tried: Users removed and reinstalled the ribbon cartridge, checked the ribbon path around the printhead, turned the ribbon knob, and tested printing again.

How this played out: The fix was ribbon cartridge seating. Users reseated the ribbon, checked that it passed correctly between the printhead and ribbon guide, turned the ribbon knob to remove slack, and printed a test line. Output became consistent after the ribbon advanced normally.

Problem: Epson LQ-2170 paper jams during single-sheet printing

What users observed: Single sheets jammed, skewed, or failed to exit correctly. The same printer could still feed continuous paper.

What was tried: Users switched lever position, aligned paper guides, used clean plain paper, checked for scraps, and tested one sheet.

How this played out: The fix was single-sheet path cleanup. Users set the lever for single sheets, aligned the guide, removed scraps from the path, and tested one clean sheet. Single-sheet printing stabilized after the paper path matched the selected lever position.

Problem: Epson LQ-2170 prints but skips lines or leaves gaps

What users observed: Users saw missing horizontal bands, skipped lines, or inconsistent dots. Impact printers can show this from ribbon path problems, printhead pin issues, paper gap settings, or dirty mechanical movement.

What was tried: Users replaced the ribbon, checked paper thickness, tested another document, printed self-test output, and compared whether the gaps repeated.

How this played out: The repair path was mechanical output isolation. Users printed a self-test, replaced or reseated the ribbon, corrected paper thickness, and checked repeated missing-dot behavior. Repeating gaps stayed with printhead, ribbon, or carriage movement rather than Windows driver setup.

Problem: Epson LQ-2170 self-test works but Windows does not print

What users observed: Users could print the printer self-test, but Windows jobs did not print. This showed the printer mechanism, ribbon, and paper feed could work independently of the computer.

What was tried: Users printed the self-test, checked the Windows port, reinstalled the driver, cleared the queue, checked parallel or USB adapter connection, and tested a simple text document.

How this played out: The repair stayed with the PC-to-printer path. Users used the self-test to confirm the printer mechanism, then corrected the Windows driver, port, queue, and cable/adapter setup. Windows printing returned after the computer sent jobs through the active port and driver.

Problem: Epson LQ-2170 Windows test page prints but business software does not

What users observed: Users printed a Windows test page successfully, but accounting, POS, DOS-era, terminal, or form-printing software did not print correctly. The driver was partly working, but the application output path still failed.

What was tried: Users changed application printer selection, tested Generic/Text Only, changed port mapping, adjusted page length, checked form template settings, and printed plain text.

How this played out: The repair path was application output matching. Users selected the active LQ-2170 queue inside the software, matched the form size, selected the needed Epson LQ or text output mode, and tested one form. Business printing became stable after the application used the same printer queue and page layout as Windows.
