I have run into a few parallel ports (mostly on laptops or old MGA add-on
cards) which work perfectly in DOS, for parallel port file transfer, but
not at all for the same thing in linux. Maybe your port is a bit
non-standard and therefore does not work in linux even for printing?
A clue is that linux is finding lp1 (which is LPT2) rather than lp0
(LPT1), which might mean it has a non-standard address. (Similarly ttyS0
is COM1 and ttyS1 is Com2).
Try to find a way to go into setup to see what the address is set to.
You can search on the internet on the computer model number and 'setup'
for help. It could be DEL, F1, F2, F10, ESC, or who knows what else, even
combinations of keys. Then look for peripherals settings and let us know
the address and whether it is the default. If you cannot figure out what
address is the default, you can set everything to defaults in setup. (But
then if you have an internal modem, disable the comport that it is set
You can also search in google/linux on the computer model number and words
such as printing and parallel port and lp1, in case other people had the
Is your parallel port onboard or on a separate card? If it is an ISA
card, you will definitely have to specify the address if nonstandard and
maybe even if standard, when you insmod parport_pc.
486s used separate ISA controller-I/O cards which could be set to
different printer port addresses and IRQs. Do you have a 486?
