Whether the driver completely spools the job to disk first, or not, depends on the Windows spool settings. If the printer properties is set to "Print directly to printer", no spooling takes place. The computer renders the image as it is sent to the printer. In this case a slow computer can make a huge difference. If spool setting is set to "Start Printing after first page is spooled," the spool process and the transfer of data to the printer occur simultaneously. Again, this will tax a slow computer. Either of the above settings could be responsible for making the printer wait for data from the computer. Only if spooling is set to "Start Printing after last page is spooled" is the CPU more or less out of the picture during printing. I say "more or less", because the cpu still controls the transfer of data from the hard disk to the parallel port, but I agree that's not likely to be the problem. > From your post, > I'm assuming that this spool > time is not the problem.

Exactly. And trying to print and spool at the same time, or print without spooling, can be slow enough to case these waits. That's why I suggested he check his spool settings. And in none of his repsonses does he indicate he checked them. ===== Bob Meyer Don't ask me why I sing this song, everything you think you know is wrong... http://www.meyerweb.net/epson __________________________________________________ Do You Yahoo!?
