Hi Till, I appreciate you looking at this and will do everything I can to help you. I appologise if its too verbose, but I want to make sure I am giving you all the information you need clearly so that you know exactly what I have done and what the outcome is.
I have updated my system and re-tested the printer. Here are the steps and the results. Part 1) Basic print tests Applied all updates Deleted Printer (System Settings - Printers) Connected Printer USB Restart PC Add Printer (System Settings - Printers - Add) The printer is detected as being connected via USB correctly "Brother MFC-7440N" I click 'Forward' to choose a driver Select printer from database option is selected Choose "Brother (Recommended)" Here is where I think the issue is... There is no Brother MFC-7440N model to choose. The nearest match is 'MFC-7450 (recommnded)' I accept that as the Model and its corresponding driver 'Brother MFC-7450 BR-Script3' I am then prompted to print a test page When I do this, the print device display says 'Receiving Data' for a brief second but nothing prints I then check the printer driver queue and it says the job was completed I then change drivers to the 'Brother MFC-7450 Foomatic/Postscript' driver On the existing settings page I choose 'Use the new PPD...' When I print a test page using this driver, the print device prints a stream of blank pages. (I can confirm the printer does have toner and is working by printing a settings configuration page manually at the print device) Part 2) Cups Error Log I have followed the instructions in the 'Cups error_log' section. I believe debugging was already enabled. I changed the driver back to 'Brother MFC-7450 BR-Script3' and tried a test print. No output from the print device. I have saved this file as "error_log-MFC-7450-BR-Script3 test page" The driver has been changed to 'Brother MFC-7450 Foomatic/Postscript' and the test print run again. The print device again prints blank pages. I have saved this file as "error_log-MFC-7450 Foomatic-Postscript test page". Part 3a) Capturing print job data I am back to the original driver "Brother MFC-7450 BR-Script3" Cleared the print queue Printed a test file (attached the original as 'test page') [code] ron@ron-Vostro-3300:~$ lpstat -o Brother-MFC-7440N-12 ron 12288 Mon 12 Dec 2011 19:42:48 EST [/code] Display cups spool [code] ron@ron-Vostro-3300:~$ sudo ls -l /var/spool/cups [sudo] password for ron: total 60 -rw------- 1 root lp 886 2011-12-12 19:43 c00012 -rw------- 1 root lp 712 2011-10-16 15:43 c00013 -rw------- 1 root lp 691 2011-10-16 15:43 c00014 -rw------- 1 root lp 796 2011-10-17 21:11 c00015 -rw------- 1 root lp 796 2011-10-17 21:13 c00016 -rw------- 1 root lp 705 2011-10-17 21:14 c00017 -rw------- 1 root lp 966 2011-10-17 21:17 c00018 -rw------- 1 root lp 966 2011-10-17 21:17 c00019 -rw------- 1 root lp 793 2011-11-08 15:21 c00021 -rw------- 1 root lp 620 2011-12-05 07:20 c00022 -rw-r----- 1 root lp 11458 2011-12-12 19:42 d00012-001 -rw-r----- 1 root lp 27 2011-12-05 07:19 d00022-001 drwxrwx--T 3 root lp 4096 2011-12-12 19:26 tmp [/code] There was two files beginning with 'd' so I have attached both d00012-001 = printout-1 d00022-001 = printout-2 (looking at the date this must be an old job) File type: [code] ron@ron-Vostro-3300:~$ file printout-1 printout-1: PDF document, version 1.5 ron@ron-Vostro-3300:~$ file printout-2 printout-2: ASCII text [/code] I have re-enabled the print queue and there is no output from the print device.
