Epson LQ-690 Dot Matrix Printer

Continuous-form printing is not obsolete — it is essential infrastructure for business operations where reliability, volume capacity, and multi-part form handling matter more than glossy marketing appeal. The Epson LQ-690 is a 24-pin impact dot matrix printer engineered for this reality: high-speed printing of invoices, reports, order forms, shipping labels, continuous-feed documents, and multi-layer carbon forms that constitute the daily operational backbone of warehouses, distribution centres, manufacturing facilities, government offices, and businesses managing large document volumes. With print speeds up to 529 characters per second (12 cpi high-speed draft), a 10 million character transferrable ribbon yield, 400 million character print head life, MTBF (mean time between failures) of 20,000 operating hours, and compatibility with single sheets, continuous paper, labels, envelopes, and cardboard, the LQ-690 delivers the speed, durability, and operational flexibility that high-volume document printing demands. This is professional-grade dot matrix printing without compromise — proven technology that has earned trust across decades of mission-critical business document production.

Why The Epson LQ-690 Is The Gold Standard For High-Volume Dot Matrix Printing

Dot matrix printing is not vintage technology — it is purpose-built infrastructure for organisations producing thousands of documents monthly. Laser printers and inkjet systems are optimised for colour graphics and speed on small document volumes. Dot matrix printers are optimised for continuous-form document production, multi-part carbon forms, rugged operating environments, and the lowest cost-per-page printing when volume exceeds 1,000 pages weekly.

The LQ-690 represents three decades of Epson impact printer engineering. Every specification is designed around high-volume reliability: 24 pins for print quality superior to 9-pin dot matrix, 106 columns for A4-width printing, 10 million character ribbon yield allowing week-long printing intervals between ribbon changes, 20,000-hour MTBF enabling continuous warehouse and factory operation without unexpected downtime, bidirectional logic-seeking print head reducing blank space transit time, 360 × 180 dpi resolution delivering professional document appearance, and transferrable ribbon cartridges enabling ribbon compatibility across multiple printers and previous generations.

This is not a compromise printer. It is a specialised tool engineered for organisations whose business depends on reliable high-volume document production.

Print Speed For Professional High-Volume Document Production

The LQ-690 prints at speeds specifically engineered for operational efficiency across multiple document types. High-speed draft mode delivers 529 characters per second (12 cpi) — printing a full page of continuous form in 5-10 seconds depending on form width and content. Standard draft mode delivers 396-440 characters per second, balancing speed with legibility. LQ (letter quality) mode delivers 110-132 characters per second, optimised for professional correspondence and invoices requiring publication-quality appearance.

For organisations printing 10,000+ pages monthly, the difference between 110 and 529 cps translates to hours of operational efficiency monthly. The LQ-690’s print speed ensures documents print without frustrating delays, enabling print jobs to complete overnight or during scheduled print windows rather than consuming daytime operational bandwidth.

The Print Speed Enhancer — a unique feature in the Epson driver — further accelerates bit image data printing (graphs, logos, images) under Windows environments by increasing print speed with slight resolution reduction. For organisations printing complex forms with logos or barcode images, this feature multiplies productivity.

24-Pin Print Head — Superior Quality And Durability

The 24-pin print head delivers print quality superior to budget 9-pin dot matrix printers whilst maintaining the operational toughness and high throughput of impact printing. The 24 pins create finer detail, crisper characters, and sharper graphics than 9-pin alternatives. Text printed by the LQ-690 appears professional and reads clearly even when documents are scanned, copied, or faxed.

The print head lifetime of 400 million characters or strokes means the print head rarely requires replacement during normal operational life. For a business printing 50,000 pages monthly (aggressive high-volume use), the print head lifetime equals 8+ years of uninterrupted operation. This translates to reduced maintenance, lower total cost of ownership, and operational continuity.

Ultra-High Ribbon Yield — 10 Million Characters Per Ribbon

In continuous-form printing environments, ribbon replacement is operationally disruptive. The LQ-690’s transferrable ribbon yields 10 million characters in black draft mode — equivalent to two weeks of continuous-form printing at 500 pages daily, or multiple months at typical office volumes. This high yield means:

• Dramatically reduced ribbon replacement frequency, minimising maintenance windows
• Longer intervals between consumable purchases, simplifying supply chain management
• Transferrable ribbon compatibility, allowing ribbons from older printers to work in the LQ-690 and vice versa, reducing waste and consumable cost
• Professional-quality printing across the entire 10 million character lifespan without quality degradation
• Reduced total cost of ownership through fewer ribbon replacements annually

The transferrable ribbon design is a practical engineering choice: organisations upgrading printers retain compatibility with existing ribbon inventories, reducing transition costs and waste.

Multi-Part Carbon Form Capability — Original Plus 6 Copies

The LQ-690 prints original plus 6 copies (7-part forms) in a single pass — eliminating the need for separate printing runs, copying equipment, or forms distribution logistics. This is transformative for organisations managing multi-part forms: order forms requiring customer, warehouse, accounting, and archive copies; shipping documents requiring driver, recipient, and office copies; invoices requiring customer and accounting copies with distributed accountability.

The impact force of the LQ-690’s 24-pin head ensures crisp, legible impressions through multiple carbon layers. Unlike inkjet or laser alternatives, the dot matrix impact creates physical impression through carbon layers without requiring special carbonless forms or multiple printing passes.

Comprehensive Media Compatibility — Sheets, Continuous, Labels, Envelopes, Cardboard

The flatbed design and dual-feed system (front single-sheet feed, rear continuous paper feed) enable the LQ-690 to handle the full spectrum of business document media:

• Single-sheet paper (90-304.8mm width, 70-420mm length, 0.065-0.19mm thickness): Invoices, letters, reports, documents
• Continuous paper (101.6-304.8mm width, 0.065-0.49mm thickness): Multi-part forms, warehouse labels, shipping documents, large batches
• Labels (single and multi-layer): Shipping labels, inventory labels, product codes
• Envelopes (No. 6 and No. 10): Business correspondence, bill payment envelopes
• Roll paper: Continuous printing without sheet feeds, enabling unattended high-volume operation
• Cardboard: Rigid media requiring impact force that only dot matrix impact printing provides

This media flexibility means the LQ-690 consolidates multiple printer functions: it can print cut-sheet invoices in the morning and continuous warehouse labels in the afternoon without equipment changes.

Dual Connectivity — Parallel And USB 2.0 For Legacy And Modern Systems

The LQ-690 provides both bidirectional parallel (IEEE 1284) and USB 2.0 connectivity, enabling integration with legacy systems using parallel ports and modern computers using USB. This dual connectivity is invaluable for organisations with mixed-age IT infrastructure: warehouses running DOS-based legacy systems, factories with parallel-connected shop-floor printers, and modern offices wanting dot matrix impact printing for specific high-volume tasks.

The 128 KB memory buffer ensures smooth printing even when host systems are intermittently busy or network connectivity is variable — important in warehouse environments where wireless networks are unstable or when printing from multiple computers to a shared printer.

Barcode Support For Logistics And Inventory

The LQ-690 supports comprehensive barcode formats: Code 128, Code 39, EAN-13, EAN-8, UPC-A, UPC-E, Codabar (NW-7), Industrial 2 of 5, Interleaved 2 of 5, Matrix 2 of 5, and POSTNET. This means the LQ-690 can print shipping labels with scannable barcodes, inventory labels with product codes, and logistics documentation with barcode integration — all with the high volume capacity that makes barcode label production economical.

Compact Flatbed Design — Desktop-Friendly High-Capacity Printer

The LQ-690 is engineered for desk and counter operation: compact dimensions (480 × 370 × 210 mm), only 6.8 kg weight, and thoughtful design that allows integration into office environments without requiring dedicated machine room space. The platen gap adjustment lever is hidden under the front cover, preventing accidental settings changes. The ruler in the front paper guide enables intuitive paper alignment.

Despite the compact footprint, the 106-column capacity and flatbed design mean the printer handles full-width A4 and larger continuous forms without pinch or alignment issues — performance that competing compact printers cannot match.

Durability Built For 20,000 Hours Of Continuous Operation

The MTBF (mean time between failures) of 20,000 power-on hours, combined with robust metal casing, means the LQ-690 is engineered for warehouse, factory, and high-demand office environments. The unit can withstand high humidity, high temperature, dust, and industrial vibration — challenges that degrade consumer-grade printers.

This durability translates to reduced maintenance callouts, fewer unexpected downtime events, and longer equipment lifecycle. For organisations where printer downtime directly impacts operations (warehouse shipping delays, factory production pauses, office invoice processing delays), the LQ-690’s proven reliability is invaluable.

Cost-Effective Operation — Low Power, Long-Lived Consumables

The LQ-690 consumes only 38 watts during active printing and 3 watts in standby mode — remarkably low for a high-volume printer. Over 24-month operation, power consumption cost is negligible compared to consumable cost (ribbon cartridges) and labour.

The high ribbon yield and high print head lifetime mean consumable cost is minimal: one or two ribbon cartridges annually for typical office use, print head replacement only after years of operation. This delivers total cost of ownership far below laser or inkjet alternatives when printing high volumes of continuous forms, multi-part documents, and barcode labels.
