Frequently Asked Questions (FAQ)

• What separates the LQ-300 layout from wide-carriage models like the LQ-2070?
  The core printhead quality is very comparable, but the footprint is optimized for smaller workspaces. The LQ-300 features a narrow 80-column carriage built for paper widths ranging from 4.0 inches up to 10.1 inches, making it perfect for point-of-sale invoices. The LQ-2070 is a wide 136-column carriage built for wide ledger formats up to 16.0 inches wide.
• What is the benefit of a 24-pin printhead over a standard 9-pin printhead?
  The 24-pin wire array uses smaller, more tightly clustered impact needles. This allows the system to fire finer dot configurations, producing true Letter-Quality (LQ) text outlines that match professional typewriter standards, while 9-pin systems output blockier Draft fonts.
• Can I print single office sheets or receipts without unthreading my continuous forms?
  Yes. This device features a built-in paper parking configuration. Toggling the physical paper release lever backs your continuous forms behind the platen area safely, letting you slide single sheets, forms, or custom corporate envelopes over the friction rollers without removing your tractor paper from the pins.
• How do I change baseline parameters like line spacing, emulation, or character maps?
  Hardware baselines are managed via physical onboard DIP switch rows situated on the printer mainframe panel. These switches allow you to choose between Epson ESC/P 2 mode and IBM 2390 Plus emulation mode, change default character sets, toggle auto-line feed commands, or shift standard page length settings between 11 inches and 12 inches.
