AGILE 5250 ALLY User’s Guide and Reference Page B-32
The qq parameter controls the print quality at the target
printer by sending one of the PFSs 2F — LOWQUAL
(qq=03h), 30 — MEDQUAL (qq=01h) or 31 —
HIQUAL (qq=02h). These PFSs are sent to the printer
only if the print quality setting is changed. Many target
printers (specifically dot matrix) place limitations on
print quality, proportional spacing, font and/or print
enhancement combinations.
The 5250 ALLY supports the dx (duplex) parameter by
sending PFS 32 — SIMPLEX, 33 — DUPLEX or 34 —
TUMBLE to the target printer whenever the parameter is
changed.
275EMUL: No operation.
Command: Set Vertical Margins (SVM)
Format: 2B D2 nn 49 tmtm bmbm
Printers: 3812, 5219
Action: Specifies top and bottom margins for subsequent pages.
The tmtm parameter specifies the top margin in 1/1440-
inch units. Valid values are 0000h through 7FFFh. A
value of 0000h causes no change to the last setting.
The bmbm parameter specifies the bottom margin in
1/1440-inch units. This parameter is not used by 3812 or
5219 printers.
IBMEMUL: Same as IBM.
When in Computer Output Reduction (COR) mode, a
default half-inch margin is added to the top margin
requested by the system.
275EMUL: No operation.
