At first I just sent the pdf file but it choked the printer and greatly slowed it down. Our network admin showed me the printer queue and showed me the size of the files that were being generated on the printer (6180). The 2.5-3MB pdf files were being ripped by the printer into postscript files that were nearly 8GB each. We were getting nearly 20 pages per minute of output (11x17) on a machine that was supposed to be doing about 90-100 per minute.
