Printronix P3000 Series - Manual (Page 20)

Operation 2–2
Basic Operation Features
On Line
The printer functions either “on line” or “off line.” When on line, the printer is capable of receiving
data and control commands from the host computer. The message display on the printer control panel
indicates that the printer is on line and shows the current print mode.
Off Line
When the printer is off line, communication between the printer and the host computer is temporarily
stopped and the message OFFLINE READY appears on the display. Set the printer off line to perform
the following tasks:
•
Display/Change Configuration Values
•
Load Paper and Ribbon
•
Run the Self–Test
•
Advance to Top of Form
•
Set Top–of–Form
•
Change Print Modes
•

Command Sets (Protocol Modes)
The P3000 Series Multinational printers respond to two different command sets (protocols): P–Series
and Serial Matrix.
The protocol is selected from the control panel and must correspond with the programming standard
used by the host computer to communicate with the printer. You can select either protocol as required
by the application. The P–Series emulation mode generates characters and graphics using Printronix
standard P–Series control code protocol. The Serial Matrix emulation mode generates characters and
graphics using Serial Matrix control code protocol similar to the IBM Graphics Printer. Refer to the
Programming chapter for detailed information on P–Series and Serial Matrix protocols and control
code definitions.
Character Set Options
Four basic character set choices are selectable from the control panel: IBM PC, Multinational,
ECMA–94 Latin 1, and DEC Multinational. Within each character set, specify the desired specific for-
eign language set.
You can also define and download a custom character substitution table to replace any symbol residing
in the character library (see page 6–31). This downloading feature is discussed in more detail in the
Programming chapter.
