This is an older NEC PowerMate Pentium 100, Phoenix BIOS 4.05.I. When this machine starts up, it send a dump of the BIOS information to the printer, page after page after page. The same information that is displayed briefly on the screen at POST (copyrights, revision numbers, system RAM checks, BIOS shadow information, etc.), is sent to the printer. I have no clue what triggered this (it never did this before), but I sure would like it to stop. The printer is an HP LaserJet 1100A, if anyone thinks that is a factor. Thanks.
