I recently found a service manual for my HP LJ 6L printer, and found it has a socket for a memory expansion, under a little cover low on the left-hand side. I'm assuming that HP will charge like a wounded bull for the upgrade, but perhaps someone here knows of another source?
It'd be nice for the kids to be able to print 600DPI graphics. It works at 300DPI (only 1MB needed), but carks on 600 DPI (needs 4MB).
