    QMS provides a command, called qstate, which is the remembered state
of your laserprinter.  Here (In /usr/spool/qpd/state) it records each 
font as it down loads it.

    qcat checks qstate to see if the desired font has been downloaded or
not, and will define a previously undefined font if need be.

    If you turn off your laser printer, you lose.

    Checking for ^Q's every ten seconds or so seems to be a cpu intensive
way of insuring the printer is on.  Why not just educate your users not
to turn the switch off?   Put a piece of tape on the switch, if need be.
Put the laser printer in a locked room.  

    I speak of the latest release of qtroff, dated May 14, 1984.
