We currently have two HP Color Laserjet 4500DN networked within our office. I do a lot of powerpoint presentations with lots of graphics. Some of these presentations are as large as 5-10Mb. I had the postscript printers drivers installed on my PC, also I make sure I use compressed graphics (JPG) as much as possible, but sometimes it still takes over an hour to print out a 12 slide presentation (sometimes longer). When at home my simple HP Deskjet 832 prints out the same slides immediately. Any way to speed up the process? Is there something our SA needs to do fix this problem?
