Since this is not helping, my statement won't help, and it is just a tip in general. But, the irony is we all asked for the deleted items to not automatically erase when ANYONE closed and reopened AC. So, now they accumulate. But, this can be changed in User Preferences.
As far as the printing goes, if you move another computer to where that computer is, does it print OK. It could be a spooling problem from AC to the printer. I would STILL upgrade the drivers.
Even though the script is there and the patient is ready to be printed, I wonder if there is anything from SQL that is not being sent quickly enough.
I could ask my SQL person to take a look at it for you. Just a hunch. I would mess around with the settings in the print driver such as print directly to printer instead of spooling, etc.
