Supporting resident fonts

Resident fonts are font resources that reside in a printer. Their use can significantly decrease the amount of data that PSF must send over slow-speed communication lines or congested LANs.

Not all printers support resident fonts, and of the ones that do support them, some support more than others. For information about the resident fonts your printer supports, see the documentation provided with the printer.

Resident fonts for different printers are put on different media. For most LAN-attached printers, resident fonts are included internal to the printer, installed and ready to use. For information about resident fonts for a particular printer, see the publications for that printer.

PSF provides two methods to access resident fonts:

• APSRFTBL (hard-coded table), used to identify resident fonts in printers that support only symbol sets—for example, the 4224, 4230, 4234, 4247, 6408, and 6412 printers.
• APSRMARK (utility), used for all other printers that support resident fonts.
