We were having a problem with printing to our color Xerox machine in the Faculty Room. A 7MB PDF file would expand to over 300MB in the queue and literally take f-o-r-e-v-e-r to print. Not sure what was the problem at first but there were alot of factors to take into consideration. I found an article on http://www.petri.co.il/forums that explained a similar situation someone else had.

Here's the link to the post:

And here's what Moderator Sorinso had to say...
"There is a big difference between PCL and PS drivers... Especially PCL6, that has some advanced capabilities that might be problem-makers when printing PostScript files. I don't recall the whole theory, and my printers' guru is out of reach at the moment, so cannot give you the whole picture.
Anyway, a PDF file is a PostScript file, that you are printing with a non-PostScript driver.
I would suggest two things:
1) in the printer's Properties, on the Advanced page, uncheck the Enable Advanced Printing Features box (see the attached screenshot).
2) install the PS driver for the same printer on the server and map it to the users.

Test these two and see which of them is better.
Good luck and let us know the outcome.

Added: also, see these articles from Adobe's site:

It turned out we had that printer installed using the PCL6 driver rather than the PS driver. The option to change the driver was grayed out so I had to add the printer locally via it's IP address. Followed the instructions in the forum post and sure enough it printed great!

With the PCL6 driver, it took about an hour to get that job to go through. Now with the PS driver installed it took only about 5 minutes! And the file only expanded to about 120MB instead of 300MB.
