Although the printer can accurately select printer
languages this way, we recommend that every job
containing printable data include an ENTER LANGUAGE
command to explicitly switch to the correct printer
language. This method improves performance and
eliminates errors in printer language switching. It also
guarantees that the correct language is always selected.
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.
