Yeah, it works fine here. I use a combination of magicfilter (debian
package) and nprint. We have a number of printers all hooked up to a
host called "ics1". I wrote a wrapper for nprint to make the
authentification and to be able to send data to nprint by stdin.
Attached are the makefiles, source, printcap, and a magicfilter file for
one of the printers.
My set up is like this:
/etc/printer/ics1/.nwclient --> authentification (holds "ICS1/username
password")
/Makefile --> rules to make a printer
/tess-ps-1 --> one of the printers.
/nw-printer.c --> source to generate a wrapper for each
printer
/tess-ps --> a wrapper binary generated by the
makefile
You will probably need to make small changes to Makefile and printcap.
Also change a magicfilter generate filter to get it to use the wrapper.
Hope the attachments help you on your way,
