Chapter 1 Product Specifications
1.1 OVERVIEW
1.1.01 General Information
The OkiJet 2010 is the first thermal inkjet product to wear the Okidata name badge.
The unit is a fully featured Windows-based, inkjet printer.
This product is a Graphics Device Interface (GDI) printer. Data leaving the computer is "preformatted" for
the printer. Very little printer circuitry is required for data handling. The received data is already formatted
for the GDI printer. RAM in the printer is minimized.
There is NO operator panel. The unit is controlled via software in the computer.
The units print resolution is 600 by 300 dots per inch. Dual printhead design allows the unit to print color
and true black without changing printheads.
The unit utilizes an edge smoothing technique called Print Quality Enhancement Technique (PQET). This
technique reduces the "jaggies" seen in slanted (italics) character set printouts.
The OkiJet 2010 printer is a "Windows Based Host Printer". The printer can print from a DOS based
program running in a Windows "DOS-based session", but it is not the best possible configuration. DOS is
a very non-graphical based operating system. The OkiJet 2010 is a GDI printer.
A parallel interface cable IS NOT shipped with the unit. The end user must purchase the interface cable
separately. It must be capable of supporting bi-directional communications to connect the printer to the
computer. This cable CANNOT be more than six (6) feet long.
