What is the recommended delete delay in the user file?

If your objects / porting set are really old, you want it to be > 0.
Otherwise you could run into problems where baan deletes the file before you're done printing it!!

Other than that, its up to you.. how long do you need it? it's not going to hurt to have it set to 999, personally, I don't even run the printer daemon and remove 'em via a cron job on a weekly basis.
