Sed in model.orig file

[support_5]

Dear all,

I have been toying with a sed that I use with no trouble on solaris in a BSD /etc/printcap output filter for a remote printer.

(We use this to handle messy postscript output from cups on a HPUX server to a XEROX docuprinter 350 that does not understand higher level postscript.)

To replace this functionality in HPUX, I have created two printers on a second HPUX server. One a dumb plotter and two a remote printer.

I direct the cups output from one server to a dumb plotter on the second server. The model.orig file is modified to include the postscript replacement sed. This printer then farms off the job to a remote printer on the same host which in turn farms off the job to the Docuprinter print server.

The insert line of the sed when included does not send output to the printer, however it works on its own.

I hope I am not making this way too complex but could not see a simpler way to do it.

Any thoughts would be gratefully accepted.

Here is model.orig file.

1. piggy-bag or dummy (redirecting) printers should have their interface script on /etc/lp/interface, not on .../model.orig
Piggy-bag printers do not only not need HPNP interfering, they don't want to.

The structure is OK, but it would be even more efficient to place the whole loop in one single lp command

# Plot the spooled files
(
i=1
while [ $i -le $copies ]
do
for file in $files
do
sed -e '{
s?/MediaPosition 1?/MediaColor(silver)?
s?/MediaPosition 0?/MediaColor(white)?
/%%LanguageLevel: 2/i %%DocumentMedia: white 595 842 0 white () %%+ silver 595 842 0 silver () %%+ yellow 595 842 0 yellow () %%+ blue 595 842 0 blue ()
}' < "$file" 2>&1
done
i=`expr $i + 1`
done
) | lp -s -d
exit 0

I found that moving this file to /etc/lp/interface was the trick.

So thankyou very much,
