LINEDEN
This is used to set the line density at the printer. This PFS is sent to the
printer whenever the System changes the line density setting in response to
an SCS Set Line Density or Set Single Line Distance command.
Although the OPTIMA normally performs vertical movement at the printer
using the VERMOVE> PFS, there are two primary reasons that the printer
may need to know the actual line density.
1) The user can cause the OPTIMA to use line feeds (the LF> PFS)
instead of the VERMOVE> PFS by setting the VERMOVE= option
(under FMTINFO: for the output port) to LINEFEED.
If the OPTIMA is using line feeds to perform vertical movement,
the printer needs to know the line density so that the line spacing
created by the line feeds will be correct.
2) If the printer supports continuous feed paper (i.e., fanfold instead of
cut-sheet) then the printer needs to know the length of the paper so
that it can move the correct distance when it receives a form feed.
Most printers set forms length as a number of lines per page after
the line density has been set. (See PAGELEN below.)
The new line density is sent as the parameter of this PFS and is
converted to the unit of measurement specified by the VER RES=
option (under FMTINFO: in the output port).
PAGELEN
The PAGELEN> PFS is used to set the length of the form, and it is sent to
the printer in response to an SCS Set Vertical Format or Set Initial
Conditions command. This is usually needed only for printers that use
continuous forms such as fanfold paper. Because the length of the form is
set in lines per page, the line density must be set correctly at the printer in
order for the forms length to be set properly. For this reason, the
LINEDEN> PFS must be set correctly in order for the PAGELEN> PFS to
work. (See LINEDEN above.)
P 5CPI
Print 5 characters per inch in portrait orientation. This PFS is sent to the
printer when the 5250 OPTIMAs page orientation algorithm has selected
a portrait orientation, and when the System has requested a font with a
pitch of 5 CPI or less (using either an SCS Set Character Density command
or an SCS Set FID through GFID command).
