Issue: User may experience an error message “the process hppostprocessing stopped unexpectedly with status 13 ” in MAC 10.4.x when trying to print.


This error is due to Disk Permission and happens mainly when users upgrade from OS 10.3 to 10.4 or run Apple Software Update. The user need to use Apple’s Disk Utility and do “Fix Permissions. ” Recreate the printer and issue should be fixed. Alternatively if users are experienced at using terminal window on MAC they can follow the below steps:

  1. cd /Library/Printers/hp/filter
  2. ls -al (to check current permissions)
  3. if current permissions on hppostprocessing are rw-rw-r–
  4. sudo chmod 775 hppostprocessing

This will change the permission to rwxrwxr-x.
