The system was built specifically to be a print server to service one HP9000 printer. It has a 20GB hard drive with three partitions /boot = 100MB /swap = 768MB / = rest of drive The spool directory is /var/spool/lpd/hp9000 Each print job varies between 800k and 1 MB. Assuming all jobs were 1MB then total space needed is only about 6GB so there should be more than enough space for the 6000 print jobs. > Another thing to think about is what "backend" is it using - CUPS? > LPRNG? - you might need to address the backend driver for that. > The back end is LPRng.

Printer memory is not an a factor. The print queue is set with a HOLDALL status. This means the jobs go to queue and stay there until they are manually released by an operator. Samba has a default setting of a maximum 1000 print jobs per queue. You can see this by running the following command: testparm /etc/samba/smb.conf. You can override default setting by adding Max Print Jobs = xxxxxx to your smb.conf file which I have done but the queue still will not hold more than 1000 print jobs. -------- Until I can figure out how to get the queue to hold more than 1000 print jobs, I have created 5 additional hold queues all servicing the same printer and we have modified the script that creates the print jobs to the spread the jobs among all the queues.
