Hi All,
Fedora32 x64
I just installed a
https://lavaports.com/serial-parallel-cards/products-pcie-bus-io-cards/parallel-pcie/
CUPS tells me the priner is not attqched.
I did a
# modprobe -r lp
# modprobe -r parport_pc
# modprobe parport_pc io=0x378,0xee00 irq=7,11
# modprobe lp
Cups shows the printer idle
Now jobs disappears as if it if printing,
but the printer shows nothing.
I am not sure that this card is being
seen as /dev/lp0. How do I
check that.
And how do I check which lp my printer is attached to?
Many thanks,
-T
After a fresh boot:
$ udevadm info -a /dev/lp0
Unknown device "/dev/lp0": No such device
Same with lp1 and lp2 and lp3
After the above modprobes:
# udevadm info -a /dev/lp0
Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.
looking at device '/devices/platform/parport_pc.888/printer/lp0':
KERNEL=="lp0"
SUBSYSTEM=="printer"
DRIVER==""
looking at parent device '/devices/platform/parport_pc.888':
KERNELS=="parport_pc.888"
SUBSYSTEMS=="platform"
DRIVERS=="parport_pc"
ATTRS{driver_override}=="(null)"
looking at parent device '/devices/platform':
KERNELS=="platform"
SUBSYSTEMS==""
DRIVERS==""
