HP Laserjet and "watermarks"

Strange.....

Are you sure LPD is not filtering the print job somehow? Samba just sends
print jobs to LPD like any other unix application, so any changes probably
happen there.

To create a filter that does not modify the print job in any way shape or
form, create a new file on Linux with:

#! /bin/sh
cat -

Make this file executable by all.

# chmod ugo+x filename

and speficy this as the input filter in the appropriate spot of your
/etc/printcap file

:if=/path/filename:

This was the reader's digest version. I hope it all makes sense.

Of course, you could just remove the input filter entirely from Printcap.
I remember that when I did that once, I could not figure out how to stop
lpd from printing 'job header' pages, but when I used the above filter,
everything worked as expected. This is no doubt to do with my inability to
grok the printcap file. It has very strange and strict format
requirements.

Hello,


I am working on a Samba server to replace an NT server for print
and file services.

I am starting with print services, as this is the most urgent
( the NT box is out of space, and the spool dir keeps getting
filled :)

We have a couple 5000 series HP LaserJets, I am testing using the
HP LaserJet 5000 GN that's on the same floor as my desk. Using the
2000 client driver for this printer seems to work fine, except for
the fact that the "watermark" feature does not seem to work.

"watermarks", as far as these printer drivers are concerned, just
print words like "Confidential" or "Draft" across the document
but are transparent, so you can still read the original document.

The interesting this is, if I print from NT 4.0 ( the current
print server in fact ), the watermark feature seems to work fine.

I am working on getting the latest drivers loaded onto my 2000 client
machine, then I will test some more. In the meantime, has anyone run
into this before?



Thanks,
Rob Helmer
