NAME
fixnt - Filter for the Windows NT postscript printer driver.
SYNOPSIS
fixnt < BADFILE.ps > GOODFILE.ps
DESCRIPTION
The Windows NT postscript driver has a tendency to make broken postscript files, that are incompatible with psutils. fixnt is a filter
that fixes these problems, allowing the use of psnup(1).
The filter takes the broken postscript file on stdin, and outputs a fixed postscript file on stdout. It has no other form for invocation
and takes no options on the command-line.
OPTIONS
fixnt takes no options.
BUGS
fixnt does not check for NTPSOct94. For a workaround, use a sed(1) command to replace 'NTPSOct94' with 'NTPSOct95', like so:
sed 's/NTPSOct94/NTPSOct95/g'
This is particularly important for Windows NT 3.5 users.
AUTHOR
fixnt was written by Holger Bauer <Holger.Bauer@topmail.de>, Michael Rath <rath@itsm.uni-stuttgart.de>, and Akim Demaille
<demaille@inf.enst.fr>.
REPORTING BUGS
Report bugs to the Authors, but avoid sending large postscript files.
Patches are always welcome; send to <bauer@itsm.uni-stuttgart.de>.
