HP QMS 1660 - Manual (Page 245)

Updated DOC
Commands
C-9 Document Option Commands
Notes If no %%IncludeFeature:install DOC command
is sent, the internal default location is used;
otherwise, this parameter, which must be
provided, specifies one of the alternate locations.
For most QMS printers, resource 6 is the system
disk.
object id
Purpose Assigns an ID to an object, such as a font, macro,
or pattern
Range 0-32767
Default 0
Format Integer
Notes The object ID can be used instead of the usual
PCL command to assign an ID. This ID is
overwritten by any ID assigned from the PCL print
job, if present. If neither a DOC command nor the
PCL print job specify an ID, the default ID of 0 is
used. Identifiers must be unique. If the ID
matches an ID for an existing object, that object is
deleted and replaced by the new object. If a
%%IncludeFeature:remove command
precedes a %%IncludeFeature:install
command, the install command is ignored (these
two commands are mutually exclusive).
