24-pin wide-carriage dot matrix printer

Sophisticated Features

Simple Operation

Speed. Quality. Versatility. The demands haven't changed, but the technology has. Dot matrix printers have come a long way, and Seikosha's innovative SL-270 AI is setting the pace. Its 24-pin printhead assures crisp, letter quality output and finely detailed graphics. And, quiet though it is, the SL-270 AI can cruise through heavy-duty printing jobs at up to 324 cps. A choice of two emulations ensures compatibility with leading software packages, while the 9 resident fonts enable you to add that professional touch to your documents. Single- and dual- bin cut-sheet-feeders (CSF) are also available as optional equipment.

Function card

A world first. This slim, plug-in card replaces the bewildering rows of DIP switches found on conventional printers. There's no need to look at the manual just to change print parameters since everything is explained on the card. One card per user speeds office work.


Three dial switches on the front panel make it easy to set paper size, font, character pitch and quality (Draft or LQ). The pushbutton controls and indicators are grouped on the right for greater convenience.

Two-way loading

Dot matrix printers are renowned for their versatility: they can accomodate a greater variety of paper sizes and types (single sheet, fanfold, multipart forms) than laser printers, but the SL-270AI goes even further. When equipped with the optional dual-bin CSF, it can handle both continuous form and single-sheet stock with amazing dexterity - thanks to paper parking and autoloading.

Tear off

Pushbutton tear-off speeds work and avoids waste by automatically aligning paper perforations with the tear bar. And the automatic bail control enables printing to start just 7mm from the leading edge.

Visible line feed

This welcome function pauses printing and feeds the paper to allow on-the spot proofing. Printing resumes as soon as the button is released.

High-speed skip

Speeds up printing of charts, tables, etc.

64 KB buffer (opt.)

Liberates your computer for other work.
