The odd
‑
numbered parameters (A1, A3, A5, and A7) specify a whole
‑
inch value. The even
‑
numbered parameters (A2,
A4, A6, and A8) specify a fraction in 100ths of an inch. Page Length and Page Width settings that are larger than the
default margin limits are ignored. The factory defaults are set to be longer and wider than the largest possible size;
thus, default bottom and right margins are used. The margins are always positioned with respect to the default edge
limits.
C1: Page orientation
This parameter designates the logical page position with respect to the physical page.
C1 value
Description
0
Portrait orientation
1
Landscape orientation
C3: Default font
The C3 parameter sets the default font. C3 can be set to one of three modes:
C3 value
Font selection
0
Font 1 for PCL emulation.
Font 8 for Proprinter and Line Printer emulations.
1–79
Sets the default font to the specified font number.
255
Sets the default font to the front panel default or the PJL setting.
L1–L8: Edge limits
The L parameters are used to vary the size of the logical page and to position it with respect to the physical paper. The
L parameters are always acknowledged in Proprinter and Line Printer emulations.
Parameters L1–L4 are always acknowledged in PCL emulation. Parameters L5–L8 are used in PCL emulation only if the
FRPO parameter R3 is set to 1. The default edge limits are as follows (all pel dimensions are 300 dpi):
Edge limit
PCL (R3=0)
PCL (R3=1) or Proprinter
Top
1/6", 4 mm, 50 pels
1/5", 5 mm, 60 pels
Left
1/4", 6 mm, 71 pels
1/5", 5 mm, 60 pels
Bottom
1/6", 4 mm, 50 pels
1/5", 5 mm, 60 pels
Right
1/4", 6 mm, 71 pels
1/5", 5 mm, 60 pels
The top
‑
and left
‑
edge limits determine the position of the logical page. The bottom
‑
and right
‑
edge limits determine
the size of the logical page. L1–L4 FRPO parameters are always interpreted with respect to the top and left edges of
the physical page. L5–L8 FRPO parameters are always interpreted with respect to a letter-size sheet of paper, with
default top
‑
and left
‑
edge limits (0.20”).
For example, to set edge limits of approximately 2 mm (24 pels @ 300 dpi) on all four sides of any
‑
size paper, the
following FRPO commands are used:
FRPO L1, 0; FRPO L2, 8;
FRPO L3, 0; FRPO L4, 8;
FRPO L5, 10; FRPO L6, 72;cmnt 11" - .2" - 10.72" = .08" = 24 pels;
FRPO L7, 8; FRPO L8, 22;cmnt 8.5"- .2" - 8.22" = .08" = 24 pels;
