GVM and HP Laserjet M506

latest kali vmware image installed on clients network and fully updated. Netdiscovery scan run to identify hosts on network. 180 IPs on network
8 of which are HP Laserjet M506 printers.

Every time GVM scans on of those printers, the printer spews out 3 pages of paper with 1 line of text on each page. Unfortunately,
this is a remote gig and the client won't provide scans of the output.

Anyone seen anything like this? Better yet, is there a way to keep it from happening?

Thanks.
