How to Disable Print Jobs from Guest

[Geoaddict]

Over the summer we have had a number of jobs sent to our printer from somewhere outside the network one of which was Nazi propaganda. Working with our IT Department the printers on our network were changed from publicly-facing to a private network. Yesterday, we had a job come through that printed a few characters on every sheet until the paper tray was empty. When I go into EWS and look at the job log, all it shows is Print and Time for the Job name and the User as Guest.  All other users are identified by their workstation name and their username. 

Is there a way of disabling the Guest user account without having everyone who has to use the printer have to authenticate first?

I do not know if this is possible.  What has happened is someone on the network loaded a print driver and used your ip address by mistake or whatever and his job was sent to your printer with the wrong coding causing all the pages. One thing if you can work with your IT department is to have them load your printer using the hostname (the host hame can be changed to whatever you want it to be) rather then the ip address. This way your printer can have any ip address just as any computer when it logs on to the network and since it will change most times when turning the printer off and then back on it will in most cases prevent what is now happening.

Thanks for the information. That sounds like a good move.  We have to be careful because the printers on our network are used in networking labs. In those labs we are teaching the students how to add printers using the IP address as well as the share name, but it might be possible to use static addresses on those days when the students are doing those particular labs.
