Example Size of a poster is: Width 60 inches, height 36 inches If you want to check your poster before printing it, print from IslandDraw into a ps- file (save as) (More: printer file, with the right settings already) and copy the file then run makeplot, a script Kevin Engle wrote to see if the orientation etc. is right. It will create a preview image, you can rotate the image, write a file in the native printer language (rtl), and even in theory send the file to the printer. the final print command for printing it downstairs will be lp -dphoto-plot -s -m poster.rtl (but call them first).
