The print file has a reset to 10 cpi at the beginning of every page.
Previously we were using smbclient with "translate -c" to convert the file from unix to dos, but when we changed to use netcat, it seems that the nulls are causing the record to be dropped.
I have tried variations of
Code:
s/\0031\0000//

with sed and vi to no avail.
What I would like is something like:
Code:
sed -f sed.inp <$file |netcat -h 192.168.1.1 -p 9100

---------- Post updated at 05:03 PM ---------- Previous update was at 04:49 PM ----------

figured it out.
Code:
tr -d "\036\000" <input >output

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>.
