        Hello.

I use Linux 2.0.30(Red Hat) and Samba 1.9.16p.
Clients are Win95, NT Workstations and Servers. I use
Linux like printserver and bridge. And I have problem
with my printer HP LaserJet 4MV with JetDirect card.
It print 1 test page( or another 1 page) and print
after it second page:
                        User: root
                        Host: LINUX
                        Class: LINUX
                        Job: testpage-a4.ps


Please help me. I want to kill this second page.
My printcap:
hpmv:\
        :sd=\var\spool\lpd\hpmv:\
        :sh:\
        :mx#0:\
        :lp=\dev\null:\
        :rm=192.168.92.4:\
        :rp=raw:\
        :if=\var\spool\lpd\hpmv\filter:
I use Postcript on the printer.
