CUPS has supported standard SYSV style printing for years.

We generally use the lpadmin command to define SYSV standard
printer interfaces, then use an interface script that takes care
of this type of thing.  Doing it this way one can even use the
same interface scripts from the SCO system.

The interface scripts we use are ones we started using back in
the Radio Shack Xenix days when printers generally required only
a LF character, but the Radio Shack/RealWorld accounting software
created printer output with CR-LF line endings which would double
space.  My interface script strips all trailing whitespace from
each line, adding back a line-ending if necessary for a specific
printer.  It also counts blank lines, sending that number of LF
characters when it encounters a non-blank.  This eliminates the
extra blank page at the end of print jobs where the application
pads output to 66 lines per page or some such.

both. The limits of tyrants are prescribed by the endurance of those whom
they oppress. -- Frederick Douglass.
