1.1 General Information
1.1.01 General Information
The Microline 590 and Microline 591 are letter quality dot-matrix printers which utilize OKISMART paper
handling. Patented Okidata technology does away with the manual head gap adjustment. The Microline
590/591 actually "reads and learns" the media you feed in, then automatically adjusts the head gap to the
optimum distance. This auto-gapping process leads to longer printhead life.
An optional, user-installable Color Kit (coupled with a customer-provided color software package) allows
the printers to add impact to graphics, charts, transparencies and text presentations.
Additional options include the Bottom Feed Push Tractor, Cut-Sheet Feeder, Pull Tractor and Serial
Interface Board.
The Microline 590 is an 80 column printer.
The Microline 591 is a 132 column printer.
Okidata's extended two year limited warranty covers the parts, labor and printhead on both printers.
The following items are included with the printer:
OKISMART Typer - software which provides the flexibility for the Microline 590/591 to function like a
typewriter on checks, labels and envelopes.
OKISMART Panel - a utility program that lets you control selected printer functions from your personal
computer.
Scalable Fonts - 14 scalable fonts, available on diskette.
Note: The OkiSmart software includes three programs:
1. OkiSmart Control
2. OkiSmart Panel Emulator
3. OkiSmart Setup
Refer to the Printer Handbook for more information.
