 Posted: Fri May 28, 2004 9:50 pm Post subject: Parallel port permission denied |
 |
|
I have the HP Deskjet 660c printer. I have already installed the hpijs driver. When i do:
| Code: | | root@localhost alex # cat test.txt > /dev/lp0 |
I recieve this error message:
| Code: | | bash: /dev/lp0: Permission denied |
CUPS doesn't give me parallel port as a device option when I try to add a printer. I don't know what I have done wrong. I have added this printer to various systems (gentoo, redhat, mandrake) without any trouble until now.
(Yes, I have done
| Code: | | modprobe parport_pc |
and
)

lp: error - scheduler not responding!

Very quickly, have you done the following?
| Code: |
1. # /etc/init.d/cupsd start
- start CUPS
2. # /usr/sbin/lpadmin -p hp -m YOUR_MODEL.ppd -v /dev/lp0 -E
- add your printer (make sure you get your model right)
NOTE: It *DOES* matter what order you put the commandline options!
3. # /usr/sbin/lpadmin -d hp
- make printer the default printer (-d option)
4. # echo "Testing" | lp -d hp
- test it
5. # rc-update add cupsd default /etc/init.d/cupsd
|
HTH  |

Well, I can't get the printer to work even without CUPS, but here is what happens when i try to do what you said.
| Code: |
root@localhost alex # locate *660c*.ppd
/etc/cups/ppd/Deskjet660c.ppd
/etc/cups/ppd/660c.ppd
root@localhost alex # /usr/sbin/lpadmin -p hp -m Deskjet660c.ppd -v /dev/lp0 -E
lpadmin: add-printer (set model) failed: server-error-internal-error
root@localhost alex # /usr/sbin/lpadmin -p hp -m 660c.ppd -v /dev/lp0 -E lpadmin: add-printer (set model) failed: server-error-internal-error
root@localhost alex # /usr/sbin/lpadmin -d hp
root@localhost alex # echo "Testing" | lp -d hp
lp: unable to print file: server-error-not-accepting-jobs
|
This kernel error message that I just noticed shows up at boot might be related to my problem:
| Code: |
can't synthesize input events
/proc/bus/input/devices |

| I think that's a hotplug error. May involve some googling for a solution. I take it that /dev/lp0 does exist. Does lpstat -t give any helpful output? |

This is the output
| Code: | root@localhost alex # lpstat -t
scheduler is running
no system default destination
|
I don't know anything about lp so I don't know the significance of this output. (good?, bad?, indicative of the problem?)

| Well that's good. It means that CUPS is running and is ok. It just doesn't like /dev/lp0. What's the file look like (i.e. the output of ls -aFlq /dev/lp0)? The other thing that may help you now that CUPS is running is to point your web browser at http://localhost:631 and click on add printer and follow the prompts. My understanding is that it attempts to auto detect printers. Give it a try. Hope that helps |

It seems that there is no /dev/lp0. 
| Code: | root@localhost alex # ls -aFlq /dev/lp0
ls: /dev/lp0: No such file or directory |
the cups http config program isn't autodetecting my printer and parallel port isn't in the options for device. (it has always autodetected my printer until now).

Does anyone else have any suggestions? I'm kind of stuck finding a resolution to this problem.
