I have been using NetBSD 1.3.2 for some months and I am very happy
with the system.
I had a very old 9 pin Panasonic printer connected to lpt0 and printed
(very)
low quality text without problems. Recently I have substituted it with an
HP
Deskjet 690C; nothing else has changed on the system. My PC has a
Tyan motherboard with a Cyrix P166+.

Now printing is very slow both with and without Ghostscript: a single page
can take two hours. I think that the PC is sending data to the printer
continuosly
(because the led flashes) but very slowly. The printed page, at the end,
is correct.
I have tried changing the cable without result. I changed the bios setting
for
the port (EPP, ECC) but NetBSD didn't recognize it any more at boot.
Finally I changed the driver from lpt0 (interrupt) to lpa0 (polled) in
/etc/printcap
and everything started working perfectly and very quickly: the same
Ghostscript
page now takes a few seconds.

Do you have any idea of what is happening? Why did lpt0 work with the old
printer and not now? Is it normal that EPP/ECC are not recognized?

Thank you very much for your help and Happy New Year to everybody
