A virtual queue is a queue that is not assigned to a device but which is tasked with retaining the print-job ready for sending it to the network device when requested by the user.
This type of queue takes effect into play when using the "Print-on-demand" activation allowing a user to send their print-jobs without designating a specific printer and retrieving their print-jobs from the printer of their choice once they have authenticated themselves to it.
To configure a virtual queue, select the group or the mode "Virtual queue" when configuring the queue (cf. Print queue configuration procedure).
Since the virtual queue sends print jobs to various devices with very different capabilities, we recommend that you configure this queue with maximum capabilities (see the Devices section : color printing, double-sided printing, and large format) in order to optimize its efficiency.
