If the connection is interrupted before your print job is complete, the
HP Fast InfraRed Receiver status indicator turns off. You have up
to 40 seconds to correct the interruption and continue the job. If the
connection is resumed within this time, the status indicator lights up
again.
Note The connection is permanently broken if the sending port is moved
out of operating range or if anything passing between the ports
blocks transmission for more than 40 seconds. (This block could be
a hand, paper, or even direct sunlight.) Depending on the size of
the job, printing with the HP Fast InfraRed Receiver may be slower
than printing with a cable connected directly to the parallel port.
Interrupting and Resuming Printing
The job interrupt and resume feature lets a user temporarily stop
the job that is currently printing in order to print another job. When
the new job is finished printing, the interrupted job resumes printing.
A user can only interrupt jobs that are printing and collating multiple
copies by connecting to the infrared (FIR) port on the printer and
sending 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.
