Abstract
The present invention detects the presence of commands requesting backchannel data in a print job and directs the flow of print jobs accordingly. If commands requesting backchannel data are detected, the jobs are routed directly to the interpreter and the print engine. If no commands for backchannel data are detected in the print job, the job may be routed to a spooler. If a print job containing commands for backchannel data is cancelled, the job data are processed through the interpreter to generate the backchannel content and are purged after the interpreter and before the job is committed to paper. Print jobs that do not contain commands requesting backchannel data are purged from the point of job cancellation.
