Hi,

I'm using CentOS 6.2, and trying to get a printer Brother-MFC-7420 to work. The printer is attached via USB.

I've downloaded and installed the drivers from the brother website, and have the printer installed in CUPS.

However, when I print anything (even the test page), the job is completed successfully (according to CUPS-log), but the printer does not print a thing.

I don't know how to debug this. Have tried to change logging to debug2, but I don't see any errors in the error_log and the access_log says: "POST /printers/MFC7420 HTTP/1.1" 200 482 Print-Job successful-ok"

Any hint to find the problem appreciated. (I should add that using the same hardware I can print on a Windows O/S, so we can exclude cable, power problems etc.)

Regards
Sebastian

Hi, welcome to LQ.

Typing
in the address bar of a browser will give you access to the CUPS server.

From there you could look for instance at the "Jobs" menu entry to check what happened to your job.

If needed have a look too to "Administration" => "Manage Printers".

If asked for a user name and password, type "root" as user name and and root's password.

Check the /etc/group file to see that user is part of "lp" group

Thanks for the suggestions.


@Didier Spaier:

Under localhost:631 I can see my jobs under <Show Completed Jobs>. They look like this:

ID: MFC7420-48
Name: Test Page
User: <my username>
Size: 1k
Pages: Unknown
State: completed at Mon 11 Jun 2012 08:31:09 PM BST
Control: <empty>

Looking at Printers on the CUPS site I can see the following printer details:

Description: Brother MFC-7420
Location: <my hostname>
Driver: Brother MFC7420 for CUPS (grayscale)
Connection: usb://Brother/MFC-7420
Defaults: job-sheets=none, none media=na_letter_8.5x11in


@EDDY1:

I checked the /etc/group file, the user was not part of lp group. Tried adding it, does not change anything.

I just noticed one possible oddity:

I checked my jobs list in CUPS and have only
Control: <empty>
for canceled jobs, not completed ones.

EDIT Did you check this thread?

I think I found the problem:

glibc was not installed and is a dependency of the Brother MFC-7420 printer drivers.

After installing via yum the printer works (prints test page).
