The Epson Stylus 9800 Plotter is located in the alcove next to the Clapp Desk, 2nd floor. We strongly recommends reserving a date and time to use the plotter.
Reservations: Most printing jobs that are ready to print will print in under 30 minutes, but please reserve 1 hour per poster in case there are problems with your document.

. Printing costs are $5.50 per linear foot for Epson Premium Glossy and Luster papers and $2.50 per linear foot for our new SiHL CAD paper. All paper costs are based on the amount of paper that was used, not the size of your poster.
Getting Started
All plotter print jobs must be sent from the computer located next to the plotter. If you created your poster on a PC, you should test opening it on a Macintosh computer in one of the computing labs around campus. You are expected to arrive at the plotter printer station with your posters ready to print. This means you may enlarge your poster to the appropriate printing size, but may not create your poster on the Macintosh computer used to send print jobs to the plotter.
