Chapter 2 Configuring the PCL-II Emulation with Control Codes

Display Functions Mode

(PCL Level I)

The display functions mode can be entered using the ESCY sequence. In the display functions mode, the printer prints representative character symbols for the control code characters instead of actually executing the control characters. In this mode, the carriage return (CR) control character will cause a CR symbol to be printed and an actual carriage return and line feed to be performed. The display functions mode can be exited by sending an ESCZ sequence. The ESCZ will be printed before the mode is terminated. Display Functions Mode “off” is the printer default state.

NOTE: The system driver may only allow the printer to print one line in the display functions mode.

When the printer is printing in high-speed draft mode, display function characters will not be printed.

Self-test

(PCL Level I)

ESCz prints the PCL-II configuration report, which shows available character sets, symbol sets, bar codes, etc.

Print Mode Selection

The standard, compressed, and double-high/double-wide print modes are selected using the ESC&1[0,2,4,8]S sequence as shown in the following table. This escape sequence affects both the primary and secondary character fonts. The default print mode is that of the default font specified from the control panel. Only one print mode is allowed per line.

Table 6. Print Mode Selection
