XPAF Support
XPAF (Xerox Printer Access Facility) accepts Advanced Function Printing
Data Stream (AFPDS) data and converts it for use by Xerox printers (4030,
2700, 4045, 3700, etc.). When installed for use with one of these printers,
XPAF expects to see a 3287-like device (such as the ALLY PLUS) at the
end of the coax cable.
The ALLY PLUS is capable of supporting two important XPAF features.
These are EBCDIC fonts and EBCDIC graphic windows. Originally
intended for EBCDIC printers, these sequences can be sent to an ASCII
printer when attached to the ALLY PLUS. These data types are sometimes
corrupted by host system forms control. The AGILE 6287 ALLY PLUS
takes this into consideration and strips away any forms control that might
corrupt these data types.
The ALLY PLUS contains special translate tables to accommodate this
feature. (These are not related to the user-definable translate and function
tables referred to elsewhere in this manual. They are located in ROM and
are unchangeable.) When either a font or graphic window is detected, these
translate tables are in effect. At the end of the font or graphic window, the
translate table is switched to the one in effect before the graphic window or
font was detected.
Xerox Graphic Windows
When the ALLY PLUS sees (UDK)gw, a graphic window is being
processed. The (UDK) is the user-defined key. Refer to the Xerox printer
reference manual for further information on this escape sequence. If the
user’s application requires this feature, and if the user would like to use the
printer in ASCII mode, Option #73 — Xerox graphic window support
should be set to 01 (enabled).
Note: If Option #02 is set to 01 (EBCDIC) or 02 (Switchable), this option
should be disabled.
