Position Aft FF (4234 only)
POSITION AFT FF allows you to select the location of the print position after a form
feed command is sent.
OFF sets the printer to print at position 2 of the first print line on the next
form.
ON sets the printer to print at print position 1 of the first print line on the
next form.
Last Char = FF
LAST CHAR = FF determines the print line position when a form feed command
is the last code encountered in the print buffer.
OFF moves to the first print position on the first line of the next form.
ON moves to the first print position on the second line of the next form.
NOTE: This option is ignored if AUTO SKIP AT END is on.
If configured as a 3287, and a form feed occurs in the middle of a print buffer, the
printer defaults to the first print position on the second line of the next form,
regardless of the setting of this option.
Null Suppression
NULL SUPPRESSION will either treat nulls as blank spaces or ignore them. If
nulls are ignored, the print position does not move.
OFF ignores nulls.
ON treats nulls as blank spaces.
FF Validity
FF VALIDITY determines if the position of a form feed command affects its execution.
OFF normally performs a form feed only if it occurs at the first print
position in a line or at Maximum Print Position +1. A form feed
command at any other position is recognized as a blank.
ON allows the printer to perform a form feed command anywhere in the
data stream.
