Hi,
Id'd like to connect a printer (via parallel or usb connectors) to my
ultra5.
Both connections (parallel and usb) lead to problems ...
Parallel:
After modprobing parport_pc the printer is successfully autoprobed
(/proc/sys/dev/parport/parport0/autoprobe shows the correct printer
type)
The printer can be installed in cups without errors ... If I try to use
it there were messages at the console and in the syslog:
lp0: ECP mode
... but nothing is received by the printer ('data' light stays dark)
As stated in the kernel documentation I switched off the FIFO option
and try to:
insmod parport_pc irq=none
still no data arrives via parallel port ...
The parallel port on the ultra5 seems to be a black whole !
USB:
Trying the USB-port (cat ... > /dev/usb/lp0) transmits some data to
the printer (i.e.
'data' light is blinking) - due to incomplete ioctl calls on sparc64
linux I receive
errors when I try printing using cups.
(see also http://lists.debian.org/debian-sparc/2004/11/msg00193.html)
I've used severel 2.6 kernels for testing ...
Any help ?

The parallel printer port driver has not worked since maybe 2.2.x, this
is a known problem. I use a network connected printer (HP2250CN) here OK.
Sorry - I have not tested USB so I cannot help there.
First make sure that you have not installed lprng, if you install lprng
and cups then neither will work. You will need to remove both and then
re-install cups.
