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.
