stretchedthin, I tried your printing suggestion (mostly):
I followed the instructions in your November 7 1:16 pm email (above) and it installed fine. I then removed Vector's hplip 3.11.7 and installed hplip 3.11.10 from the repository and got the error "hplip: Depends: avahi >= 0.6.30." Most likely this is because I haven't updated to the latest VL 7 beta. ... I have reinstalled hhplip 3.11.7.
but it didn't work, for me, using this older version of VL7 (see signature below). The problem, since VL6, has been this: I use a laptop (see signature below). I have to connect to my HP Laserjet 4mplus via the usb port. Cups doesn't see the printer. I suppose if I knew the ppd and all that I could get past this point. But in VL6, I didn't have to do anything other than ask cups to find a new printer and cups came up with an option to select usb. I would select that option, and continue, which eventually brought me to a page with all sorts of printers. I would find the hp section, scroll down to my printer and install. I can't do that and have never been able to do it. As I put VL7 on this new laptop some months back, I can't really say whether its a samsung problem or a cups problem or a VL problem. I just know it doesn't see the printer. If I had a parallel port, I am sure it would work.
But thanks much for your and Vector's efforts.
I strongly suspect that it is something different in cups that is causing my problem.
