Printer and Parallel port


I'm having trouble instaling my printer.
It's a Epson C42SX (parallel port) on a Slackware 9.1 kernel 2.6.3.
Cups is installed and also gimp-print.
When I try to add a printer on Cups it does not show a Parallel port.
So I chose LPD/LPR Host or Printer, and inserted /dev/lp0 on the URI.
But didn't work.
this is the output of my lpinfo -v
# lpinfo -v
network socket
network http
network ipp
network lpd
direct scsi
serial serial:/dev/ttyS0?baud=115200
serial serial:/dev/ttyS1?baud=115200

Any hints why my parallel port is not beeing recognized?

And also, my dmesg is showing this.
lp: driver loaded but no devices found

both modules are loaded
lp and parport.

the devices are here
# ls -l /dev/lp*
crw-rw---- 1 root lp 6, 0 1995-04-27 20:17 /dev/lp0
crw-rw---- 1 root lp 6, 1 1995-04-27 20:17 /dev/lp1
crw-rw---- 1 root lp 6, 2 1995-04-27 20:17 /dev/lp2
-rw-r--r-- 1 root root 6 2004-02-20 23:32 /dev/lpt0

And I inserted my user on lp group.

OK I did it.
I just had to modprobe parport_pc
But I don't know why it was not loaded with the lp and parport modules during boot.
Where should I put it to load with the others?

Parallel printer help

Hello ...anyone?


I am having a similar problem with my parallel port/printer : CUPS will not recognize my parallel port.

I am installing a HP LaserJet 5MP on RedHat 9


Here is some output...

[root@localhost share]# lpinfo -v

direct usb:/dev/usb/lp13
direct usb:/dev/usb/lp14
direct usb:/dev/usb/lp15
network smb

When entering 'modprobe parport_pc", I get the following:

[root@localhost share]# modprobe parport_pc
/lib/modules/2.4.20-8/kernel/drivers/parport/parport_pc.o: init_module: Device or resource busy
Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
You may find more information in syslog or the output from dmesg
/lib/modules/2.4.20-8/kernel/drivers/parport/parport_pc.o: insmod /lib/modules/2.4.20-8/kernel/drivers/parport/parport_pc.o failed
/lib/modules/2.4.20-8/kernel/drivers/parport/parport_pc.o: insmod parport_pc failed
[root@localhost share]#


When I modprobe 'lp' and 'parport' , I get no response, even though 'lsmod' includes them in its list.


At this stage...the newbie says...."Help??"

I was also getting the message "lp: driver loaded but no devices found" in ZipSlack 10.2 but found a solution on another forum. Just thought I'd share it here.

Insert the following lines in the file /etc/modules.conf:
alias /dev/printers lp
alias /dev/lp* lp

Remove the comments from the "Parallel Printer Support" section in the file /etc/rc.d/rc.modules.

When the system reboots, the following message appears:
lp0:using parport0 (polling).

Printing using the command "cat file > /dev/lp0" now works.
