bart if you want to send me some of the high res photos i can test out my plotter to see how well the photos turn out.. its supposed to be able to print at 4800 dpi in color and handle up to 5000 pages a month, i may be able to do the printing out of my house... calendars would be printed on 11x17 paper so each photo and calendar grid would be 8-1/2 x 11
