OK, that's not the same thing.  Jobs can be created using the IPP
Create-Job and Print-Job operations using the "job-hold-until"
attribute, so that they are held before printing.

Holding the job after it has been created allows it to start
printing in that 1-second window.  The only way to atomically
hold a job for printing is to create it with the job-hold-until
attribute.
