PRESCRIBE commands
Even though the L parameter values are programmed with respect to letter-size paper, the edge limits are applied in
the same manner regardless of the actual paper size. The following formulas can also be used to derive the appropriate
L values:
L1, L2 = top_edge_in_pels/300
L3, L4 = left_edge_in_pels/300
L5, L6 = (3240 - bottom_edge_in_pels)/300
L7, L8 = (2490 - right_edge_in_pels)/300
Where L1, L3, L5, and L7 are the whole‑inch values, and L2, L4, L6, and L8 are the fractional values in 100ths of an inch.
Notes:
• Each Kyocera model has different values stored for the top‑edge limit (L1, L2) and the left‑edge limit (L3, L4)
even though the actual edge limit distances, with respect to the edge of the page, are the same for each printer.
This makes it necessary to generate separate FRPO initialization files for each model of Kyocera printer in those
accounts that need edge limits other than those that came with the printer. The corresponding L1–L4 values
need to be derived for the PRESCRIBE emulation option for those who need edge limits other than the defaults.
Any existing FRPO commands that set the bottom‑ or right‑edge limits should be compatible, and should not
have to be recomputed for Lexmark printers.
• The unprintable areas (no-print regions) for most Lexmark laser printers are 1/6 inch (or 50/ 300 pels) from the
respective edges of the paper (except for A4, which has 40‑pel left and right areas). Even though edge limits are
outside of these unprintable areas the no-print regions are fixed and clipping may occur. The no-print clipping
regions are automatically reduced when the L parameters are sent to reduce the edge limits. The minimum no-
print size is 24/300 pels or approximately 2 mm (for all 4 sides).
• The FRPO INIT command does not reset the L parameters.
• The L2 parameter can be negative. (for example, !R! FRPO L2, -33; exit;)
N4: Duplex binding
This parameter specifies whether a print job id printed on one side (simplex mode) or on both sides (duplex mode) of
the paper.

P1: Default emulation
The factory default printer emulation is PCL. This PRESCRIBE emulation option supports a level of PCL 5e that is
compatible with the HP LaserJet family of laser printers. Although the PRESCRIBE emulation option supports only one
base emulation, support for IBM Proprinter (P1=1) and Line Printer (P1=0) were added for applications that rely only
on the Proprinter margins and default environment settings. They never actually use any Proprinter escape sequences
(the application only exits PRESCRIBE to print text, line feeds, carriage returns, or form feeds). P1 can be set to only 6
(PCL), 1 (Proprinter), or 0 (Line Printer).
The default environment setting differences between PCL, Proprinter, and Line Printer include the following:

Duplex off
