Can't print to HP PSC 1210 from HP Omnibook 4150 running Knoppix

Hi,
I've followed the instructions to the letter (I think!) and hpoj-0.91 is 
installed with no errors, but nothing prints.

Background:
- Laptop is an HP Omnibook 4150
- O/S is Knoppix (Debian) on kernel 2.4.24-xfs, freshly installed
- Printer is a brand-new HP PSC 1210
- All the prerequisites are there, as called for in the 'compiling and 
installing' section of the manual:
     gcc 3.3.3
     g++ 3.3.3
     ld 2.14.9.0.0.7
     perl 5.8.3
     bash 2.05b
     libusb-0.1.so.4
     xscanimage
     xsane

- when I installed libusb-dev, it required the line "none /proc/bus/usb 
usbfs defaults 0 0" to be added to fstab, so I did, and it mounts 
successfully on bootup.

- I downloaded & compiled the hpoj tarball yesterday into /usr/local:
    -   "./configure" reported no missing dependencies.  It did state 
that the xojpanel is disabled (that's OK - this printer doesn't support 
that anyway)
    -   "make install" proceeded ok, returning no errors except for:
      a.  a warning about setting the $PATH.  I checked in /etc/profile, 
and /usr/local/bin and /usr/local/sbin are both already in the PATH. 
(I don't have a profile.d file that I can find)
      b.  A warning to update the rc#.d files (I did)

-I ran "ptal-init setup" as root from a console.  It identified the 
printer correctly, and there were no errors.
- "ptal-devid", "ptal-ph", "ptal-connect -service ECHO" all worked as 
expected

Problems:
-----> "ptal-print </dev/null" returned a 'successful' message, but 
there was no action on the printer - not so much as a blinking light.

-----> Next, I set up the printer using CUPS, found the "PTAL" device 
and tried all the listed drivers (there were 3 suggestions for HP 
deskjets)  Test pages were always reported successful by CUPS, but 
nothing printed.


Any and all help will be VERY much appreciated.

Thanks!
