	The best solution to "Error 20" is to buy an Apple LaserWriter.
It's got a full Meg of RAM (more?) and you can indeed send it a full page
bit-map at 300 dpi.  We regularly use ours to print 512 x 512 x 8-bit
images that take up about a 7-inch square area of the page, with random
text on the rest of the page.  The LW also talks PostScript, which is worth
more than you can understand until you're actually used it.

	Of course, the LW costs more than the LJ (about $4k compared to
about $2.5k?).  You get what you pay for.  Disclaimer: other than being a
satisfied customer, I have no connection with Apple.  Come to think of it,
I'm a satisfied customer of HP too, I just don't buy laser printers from
them.
