CAUTION
Problems can occur from the misuse of the persistent setup feature.
Keep the following in mind when using this feature:
• Only PostScript setup modules can be persistently loaded. Other
data types cannot be persistently loaded.
• A setup module can exceed the printer’s virtual memory. Different
models of printers have different capacities. For example, a setup
module can overwhelm a printer with too many fonts.
• A shared network printer can be used from several nodes in the
network. Make sure the same setup module is loaded from all the
nodes that access the printer to ensure consistent print results. If
you required different setup modules load the setup module with
each print job, using either the /SETUP or /FORM qualifier.
• Improper PostScript coding in a persistently loaded setup module
can cause unexpected results that are difficult to analyze. Also,
because the code remains in the printer until the printer is turned
off, users from different systems may have print jobs fail with
unexpected results, but would not be able to determine the cause of
the problem.
7.7 Changing the Default Character Set for PCL and
Proprinter Print Jobs
The default character set for PCL files is Roman-8. The default character set
for Proprinter files is code page 437, character set 1. To change the default
character set, use the following procedure:
1. Create one device control library for PCL setup modules, one for Proprinter
modules, and another library for PostScript modules. Use the following
commands:
$ LIBRARY/CREATE/TEXT SYS$COMMON:[SYSLIB]PCL_LIB
$ LIBRARY/CREATE/TEXT SYS$COMMON:[SYSLIB]PRO_LIB
$ LIBRARY/CREATE/TEXT SYS$COMMON:[SYSLIB]PS_LIB
