Introduction

The P6000L/P6200L printers can be configured by the user from the control panel to respond
to Printronix P-Series or IBM Graphics Printer Serial Matrix control codes. This dual com
patibility allows the programmer to choose one of two standard protocols. If equipped with the
Intelligent Graphics Processor (IGP) option, the printer will respond to the Special Function
Control Character and IGP commands as described in the IGP User's Reference Manual. This
chapter describes:

Overstrike Mode
Data in the print buffer can be underlined or overstruck when the carriage return code (hex
0D) is configured for carriage return only (not carriage return and line feed). Any printable
character in the data stream can overstrike printable characters or spaces already loaded in the
print buffer as long as a paper motion command (ie: line feed, form feed) has not been re
ceived. An example of overstriking and underlining characters is shown in Figure 6-1.
Key
[Sp] = Space (20 Hex)
LF = Line Feed (0A Hex)
* NOTE: The printer must be configured for carriage return only. If
configured for a carriage return and line feed on receipt of the CR code, the
contents of the buffer will be printed.
