Blank pages after each job

[Kevin]

Hi Folks-

I have a feeling this is a FAQ, but I don't see it answered anywhere.

I saw Kevin Berry's post on 11/1/04 about the same thing, but never saw
it answered.  I'm hoping my post will fare better.

Is there a default setting in CUPS to generate a blank "separator" page
after each job?  If so, how does one turn it off?

I have two printers being made available in three different ways over
the network:

Printer A is connected to /dev/lp0 on a linux server and is made
available over the network directly with ipp.

Printer B is connected to LPT1 (parallel printer port) on a Win2KP box
and made available over the network with the TCP/IP Printer Service
(LPD) and as an SMB share.

I configured a linux client to print to all three of these with cups
configured locally on the client through port 631 of localhost.
Printing works fine with both printers and with all three methods.
However, Printer A does not spit out a blank page after I ask it to
print a test page via the web interface of cups from the client's
localhost and Printer B _does_ spit out a blank page after I ask it to
print a test page via the web interface of cups from the client's
localhost.  When I use a windows client to print a test page to Printer
B, (SMB shared to the windows client), I don't get a blank page after
the test page.

I configured Printer B on the linux client through the cups web pages on
localhost:631 with a ppd file that was for the exact printer that I'm
using (HP Color LaserJet 4550 Postscript) so I'm skeptical that it's the
wrong ppd file for the printer.

It seems most likely to me that there is some cups setting to print an
extra page after each job that is turned on in the linux client's cups
settings, but turned off in the linux server's cups settings (to which
Printer A is connected at /dev/lp0), but I've hunted through
configuration files on both machines and don't see anything likely.

I've looked through cups docs via localhost:631 and man pages, but don't
see anything.  I've looked at this list archives and googled for this,
but alas... nothing.  I saw someone write about occasional (as opposed
to always) extra pages after print jobs and they mentioned that the ppd
file is wrong in this case, but this ppd file comes from foomatic and is
exactly the right one for this printer.

Any help please?  Is there a setting like I think there is or is the
problem elsewhere?  If it's a wrong ppd file, which one should I use?
Or should I be using Advanced Intelligent Printing with PostScript
Driver Download described in the samba docs?


TIA-
