pci-e parallel port problem

I have an old parallel matrix printer that i had connected to my pc by a usb to parallel adaptor because my pc does not have a parallel port. This worked intermitently (as most seem to do) so i bought a pci-e parallel port card.
Pclinuxos seems to detect the card but i cant get the printer to work.
The computer is dual boot with windoze 7 that runs the printer perfectly.

I also tried some old live linux CD`s.

OpenSuse 11 does not detect parallel port.
ubuntu 10.4 wont print
Pclos detects parallel port but not printer
ubuntu 9.04 WORKS PERFECTLY

Flags: bus master, fast devsel, latency 0, IRQ 17

[j at localhost ~]$ echo "test" > /dev/lp0
bash: /dev/lp0: Device or resource busy
[j at localhost ~]$





Any ideas?

Why does ubuntu 9 work and ubuntu 10 and other linux does not?

I really don`t want to boot w7 just to print and i dont want a new printer cos i like old dot matrix printers! Mega cheap to run and far more reliable than an ink jet.
