HP PCL/PJL reference (PCL 5 Printer Language) - Technical Reference Manual Part II

EN CO, Comment 19-19
The IW command lets you control the size of the HP-GL/2 printing
area so that you can draw a particular portion of a drawing. You can
leave the rest as white space, or use the remaining area for labels, or
another drawing. Refer to “The Vector Graphic Limits” in Chapter 17,
and the IW command description later in this chapter.
CO, Comment
This command allows comments to be inserted within an HP-GL/2
command sequence. The comment string of the CO command must
be delimited by double quotes.
CO “text ... text”
HP-GL/2 comments are ignored by the printer.
DF, Default Values
This command returns the printer’s HP-GL/2 settings to the factory
default settings. Use the Default Values (DF) command to return the
printer to a known state while maintaining the current locations of P1
and P2 (unlike the IN command). When you use DF at the beginning
of a command sequence, graphics parameters such as character
size, slant, or scaling are defaulted.
DF [;]
The DF command resets the printer to the conditions listed in Table
19-7.
