Interrupting and resuming printing
The job interrupt and resume feature lets you temporarily stop the job
that is currently printing in order to print another job through an FIR
connection. When the FIR job is finished printing, the interrupted job
resumes printing.
To interrupt the job at the printer, connect to the FIR port on the
printer and send a job to the printer. The printer stops printing the
current job when it reaches the end of the copy it is printing. The
printer then prints the job sent over the FIR connection. When the
printer is done printing that job, it resumes printing the original job
with multiple copies where it left off.
