We have a Xerox printer in our office, when the printer is scanned by Qualys it prints out a test page. Is their a specific plugin or QID that is associated with this particular activity?
Here are two related articles (both indicate a software update on the Xerox printer will fix):
Xerox Workcentre 7220i - Printer Output During Scan
Thank you for the suggestion Robert. I did confirm that printer was on the latest version of firmware, however the issue is still occuring. The particular device this is occurring on is a XEROX WorkCentre 7855.
If you are still seeing the issue, then I recommend you file a case with Qualys Support, and they can have some technical experts help you.
you likely have direct print over TCP port 9100 open, which means anything sent to that port or whatever the designated port is will initiate a print job. this can also cause mass print jobs to run too and is a gap in locking down printers.
