Display Functions, like the Transparent print command, prints Escape
sequencesand control codes without actually executing them. But Display
Functionspays attentiontoCarriage Return codes, sotextlooks morelikethe
way itnormally prints. Display Functions also prints commands as blanks,
not as symbols.
DisplayFunctions actuallyinvolves two Escape sequences,one to turn it on
andanother to turn it off. To turn on Display Functions, send this command
just before the data you want displayed:
<ESC> Y
And to turn off Display Functions, send this command at the end of the
displayed print data:
<ESC> Z
That Escape Zsequence itselfprints as ablank followed by aZ.
4.5.8 Font control
TheFont Control commandhas two main functions: definingafont’s status,
and deleting fonts.
You can make afonteither permanent or temporary with the Font Control
command.This helps youcontrol whichfontsyou delete, aspermanent fonts
do notget deleted when you reset the system. The permanent or temporary
statusyou give to afont will apply only to the font you last specified, using
one of the font ID commands described above.
When your printer’s memory gets stuffed with fonts, you can also use this
command to delete some of them. You can only delete fonts you’ve
downloaded,as internalandcartridge fonts areneverdeleted. Notext willget
lostwhen you delete afont, even when that font is on an unprinted page in
the printer’s memory.
