Resetting the Print Environment

Resets are used to return the printer to a known environment. Depending on the type of reset performed, the printer returns to either the User Default Environment or the Factory Default Environment.

Printer Reset

A Printer Reset restores the User Default Environment and deletes temporary fonts, macros, user-defined symbol sets, and patterns. A Printer Reset is performed by sending the ECE command, or through the printer’s control panel (see the printer User’s Manual). The Printer Reset command is described in Chapter 4, PCL Job Control Commands.

The ECE command prints any partial pages of data that may have been received. The control panel [RESET] discards any formatted pages which have not yet been printed.

Both resets ( ECE and the control panel [RESET] ) return the HP-GL/2 settings to their default values. ECE used in HP-GL/2 mode returns the printer to PCL mode in addition to resetting the print environment. The HP-GL/2 IN (Initialize) command resets HP-GL/2 settings to their default values without affecting the PCL settings (refer to the Initialize command described in Chapter 19, The Configuration and Status Group, for additional information).

Notes	Hewlett-Packard strongly recommends the use of both the ECE
	command and the EC%–12345Xcommand (Universal Exit
	Language/Start of PJL — also referred to as the UEL Command) at
	the beginning and end of each job. (The order of these commands is
	critical. Refer to Table 4-1 for an example of their usage.)
	The UEL Command (E %–12345X) has the same effect as the	E	E
	C	C

command, and also enters PJL Mode of operation for printers that support PJL (refer to “Universal Exit Language Command” in Chapter 4 for more information). The ECE command should be included to ensure backward compatibility (the UEL command is ignored if received by a printer that does not support PJL).
