Does anyone know what the ESC-sequence is to reset the HP LASERJET
SERIES II to a powerup condition? If it is not an ESC-sequence, does
anyone know how to do it without physically getting up and pressing
the RESET-key on the printer? Thanks.

The use of the "Reset" sequence or operator panel commands will NOT clear soft fonts and macros that have been declared as "permanent" when they were downloaded into the LJ. Instead of physically doing a poweroff/poweron sequence, send the following 12-byte stream to your LaserJet: ESC E (the traditional Reset) ESC *c0F (delete all soft fonts {that's a zero eff}) ESC &f6X (delete all macros) The ESC is really the escape character (hex 1B). Case is significant; use upper and lower case characters exactly as shown.

Try ESC-E. That's what the book says, but it isn't too explicit about how thoroughly it resets the machine.
