Under normal circumstances, print jobs are sent to the MyQ server where they are stored and wait for release. With Device Spooling enabled, a print job is sent directly to the device and saved to its hard disk. It waits there to be released in the standard way.
Locally spooled color jobs are not displayed when color print is restricted.
Even though it is possible for a user to use both print to server and Device Spool, this option is not recommended. The following problems may appear: jobs are not sorted and printed in the correct order, the terminal display might not be correctly refreshed.
