Trouble printing to HP PSC 1610 on Windows from openSUSE 10.1

Hi, I am having trouble printing from linux. I found a Slackware
package to fix printing to HP PSC 1600's, and installed it and followed
the instructions. But whenever I print to it, it just prints out a few
lines of PostScript (%!PS-Adobe-1.0 followed by some more stuff). Then
I added it as a Samba printer and set it as a "psc 1600 series" on
YaST. However the same problem is still there. Can someone help me fix
it please?
