Compatibility Option 5: 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 (the default) ignores nulls.
ON treats nulls as blank spaces.

Compatibility Option 6: Form Feed Command Position

FORM FEED COMMAND POSITION determines if the position of a form
feed command affects its execution.
OFF (the default) normally performs a form feed only if it occurs at the
first print position in a line or at Maximum Print Position +1. (The
Maximum Print Position is the line length.) 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.
Compatibility Option 7: Automatic Form Feed at End of Print
Buffer
AUTOMATIC FORM FEED AT END OF PRINT BUFFER specifies
whether or not to perform an automatic form feed at the end of a print buffer.
OFF (the default) performs an automatic new line command after
completing a print buffer (unless a form feed, new line, or carriage return
command was the last one executed). The printer is set to print at print
position 1 of the next line.
ON performs an automatic form feed after completing a print buffer
(unless a form feed command was the last one in the buffer). The printer
is set to print at print position 1 of the first line of the next form.
