Command Definitions (FCONTROL - FLOCK)
FDEVICECONTROL
The following bits are ignored if set to zero:
parm1 (0:1) 1 = Multicopy form overlay feature on
parm1 (1:1) 1 = Multicopy form overlay feature off
parm1 (2:1) 1 = Reserved for the operating system
parm1 (3:1) 1 = Redefine physical page length
parm1 (4:1) 1 = Redefine number of copies per page
parm1 (5:1) 1 = Reserved for the operating system
parm1 (6:1) 1 = Reserved for the operating system
parm1 (7:1) 1 = Reserved for the operating system
parm1 (8:8) New physical page length in units of 0.25 inches; cannot
be less than 3.0 inches (a value of 12) or greater than 17.0
inches (a value of 68)
parm2 Number of copies to print; if number exceeds the
maximum defined in
parm2 of controlcode 132, only the
maximum number of copies is printed
FDEVICECONTROL accepts page length values that are in multiples of 0.25
inches, but the Hewlett-Packard 268x printer is able to produce only pages
that are multiples of 0.5 inches. For this reason, use only even values in
parm1 (8:8) (bit (15:1)=0).
134/I16V Download/delete character set:
parm1 (0:1) 0 = Download character set identified in right-hand byte of
parm2 , Hewlett-Packard 268x 1 = Purge character set
identified in right-hand byte of
parm2 , Hewlett-Packard
268x
parm2 (0:1) 0 = First record of a load 1 = Continuation of previous
record
parm2 (8:8) Character set identifier; integer from 0 to 31
If there is an attempt to download a character set having the same
identifier as one existing in the printer, then the Hewlett-Packard 268x
purges the existing character set and repacks the user area before loading
the new font. However, before the modification of the user area, the
Hewlett- Packard 268x prints all data currently in its buffer, as it does
when a character set, form, or vertical format control set (VFC) is loaded,
overlayed, or deleted.
135/I16V Download/delete form:
parm1 (0:1) 0 = Load form set identified in the right-hand byte of
parm2
1 = Purge identified form set from the Hewlett-Packard
268x printer's memory
parm2 (0:1) 0 = First record of a load
