Disconnect all devices from the computer then do the following:
Boot up from your Snow Leopard Install DVD while holding down the "c" key.
Select the language you wish to use, and then choose "Disk Utility" from the menu bar.
Your HD should appear in a panel on the left hand side of the window which opens. Select it and then click on the "repair disk" button in the right hand section of the window.
Once this process has been completed restart your computer and repair permissions directly from Disk Utility.
If Disk Utility is unable to complete the repair, you will need to use a stronger 3rd party utility like DiskWarrior, Techtool PRO (not Deluxe) or Drive Genius.
Reconnect your printer. If still not printing try the solutions mentioned below.
Install the gimp drivers. CLICKY CLICK---> http://gimp-print.sourceforge.net/MacOSX.php, repair permissions and restart your computer.
Thanx do much for taking the time. I had tried all the points you suggested as well as runing backendrestore, the maxosxupd10.6.8Supp, ran the repair and verify/repair permissions etc.
I tried once again to print, after resetting (purging) all my printers and though the HP Laserjet 1300 shows up and you can route jobs to it, I get an error with the following message in the log:
E [09/Apr/2013:15:07:31 -0800] Unable to execute /Library/Printers/hp/filter/hpPostProcessing.bundle/Contents/MacOS/hpPostProces sing: no execute permissions (0100664)
E [09/Apr/2013:15:07:31 -0800] [Job 3] Unable to start filter "/Library/Printers/hp/filter/hpPostProcessing.bundle/Contents/MacOS/hpPostProce ssing" - Operation not permitted.
E [09/Apr/2013:15:07:31 -0800] [Job 3] Stopping job because the scheduler could not execute a filter.
I tried to check but there are no such directories.
Thank you for any help!
PS I should add that I have a second HP printer, a PSC750, that's also on a USB connection and prints fine. I had also installed the gutenprint5.2.9.
OK, it seems that the Laserjet 1300 from HP was not included in the 10.6.8 update but the PSC750 was which is why I was able to print to one but not the other.
