A Postscript printer has to keep, at minimum, 8.5x11x600x600 bytes of RAM, about 33 megabytes.
Actually, postscript printers rarely have enough memory to hold a bitmap image of the whole image. First of all, its only a little over 4MB, since there are 8-bits per byte. But, the printers usually store encoded formats, and do a last bit of rendering as the page is coming out. My old HP would actually degrade high-resolution pictures because it didn't have enough memory. My full color, postscript 600x600DPI HP color laserjet only has 32MB of RAM. It's still a lot more than you need for PCL or something proprietary. Many printers (especially inkjet) expect the host to render everything and send the image as it is needed.
