The full specs are here.
We stock 8.5x11 and 13x19 in paper. The print resolution is up to 4800 x 1200 dpi color when printing from 1200 input dpi. The printer can do borderless printing.
The costs are $4 per 8.5x11 sheet and $6.50 per 13x19 sheet. We expect users to log all prints. We don't stock a lot of paper so give us notice if we need to buy extra.
When printing from our macs, specify "Borderless" in page setup if that is your desired print type.
