Basic Terminology

Printer Commands

Printer commands are signals sent by your computer to the printer which guide and control

its operation. They usually begin with the ESC character and can be sent in decimal, ASCII,

or hexadecimal form.

Emulations

The ML320/321 E/I printers emulate the Epson FX printer and the IBM Proprinter printer (the

factory default). The ML320/321 Standard printers have the Okidata MICROLINE Standard

emulation.

Printer Drivers

Commercial software packages use printer drivers to control the appearance of printed

documents. A printer driver is a set of printer commands which cause the printer to perform

various functions at the request of the software. When you use your printer with a software

package, you must use the software to select a printer driver which is compatible with your

printer.
