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 ?
