Sorry, I do not actaully have a LJ 1000 and am not familar with other drivers that might be compatible. Someone else here may have an idea, or you might try asking in the Laserjet section of the HP Business Forum. I did a cursory search and turned up a lot of questions but no solutions. The Laserjet 1000 is a host based pritner so it is not compatible with PCL drivers that most Laserjets use. The closest thing to a solution was a suggestion to print to PDF and then have the LJ 1000 connected to another (non-64 bit OS) computer, see here for details. It is the post by Itig99.
