H The Error Handler - QMS -ps 800+ User Manual

which control the values of the timeouts are described in
Part V, "POSTSCRIPT Addendum", Section C.
The job timeout limits the total amount of time that the
printer will execute a job. This is to protect the QMS-PS
800+ from being tied up by a POSTSCRIPT program that
runs for an unexpectedly long time (or forever).
The manual feed timeout limits the amount of time the
printer will wait for a sheet of paper to be inserted into
its manual feed slot when the printer is in manual feed
mode.
The wait timeout limits the time the printer will wait
to receive additional input for a job that is already in
progress. This is to protect the QMS-PS 800+ from
being tied up indefinitely by a host computer that crashes
or is disconnected in the midst of sending a file to the
printer.
If a job or wait timeout expires, the POSTSCRIPT soft-
ware executes the timeout error. This causes the current
job to terminate. Setting a timeout value to zero gives
that timeout no time limit (i.e. it will never timeout). It
is generally a good idea to leave the job timeout at its
default value of 0, especially when printing long files.
The timeout facility is not ordinarily enabled when the
QMS-PS 800+ is in interactive mode.
H The Error Handler
Type this program into a file exactly as follows then send
it to the QMS-PS 800+. Whenever the printer encounters
an error while in QMS POSTSCRIPT Mode, it will print
a page identifying the error. It must be sent again to the
printer after each power-off.
