Printer Status Readback
When requesting status information from the printer, ignore all status
information that you did not request. For example, if you request INFO
ID and get USTATUS or some other response, ignore that response
and read the next one until you receive the INFO ID response.
Due to other printer users in a multi-user system, there may be
situations where the printer status buffer overflows, and instead of
receiving requested status information, you receive the 10010 error.
(For the HP LaserJet 4 and 5 family printers except for the LaserJet
4PJ, the 30010 error is returned for “buffer overflow” instead of the
normal 10010 error code. HP LaserJet 4PJ and 4LJ Pro printers
return the 10010 error code.) Reading the 10010 or 30010 error
clears the status buffer; if you receive either error, resend the status
request.
