Print Job From A Guest

[Sozuk]

Hello Everybody,

It's been a month, we have several print jobs from a "guest" account. These print jobs are done at night.

Our printers are on a print server.
With security just "Authenticated user".

We tried to put some local ones out of the server, but even on these printers there are impressions per guest.

These impressions make pages with characters and symbols on the pages.

We looked at the print logs and we see job names like: print 01:02 with the date and time at 01:02. And the author: Guest.

For other impressions, we can see who makes the impressions and the names of the impressions (ex: CurriculumVitae.pdf).

Would you meet the same worries? And how did you solve it?
I can not find on the web, more information.

Thank You for your time,

Hi @Sozuk,

Welcome to the HP Support Forum!

Go to Printer Prints Unwanted Advertisements (Spam) > Step 3: Secure the Wi-fi Network. 

Let me know if that helps!

I have a guess. 

Often in a corporate environment the IT Security group will run a tool on the network that checks to make sure devices on the network are secure.  As a part of that check ports on devices are scanned.  It could be that that port scan is being interpreted as a partial print job.  After a few minutes the printer will terminate the print job and eject the page.  The characters adn symbols are likely a side effect of the scan process.

Hello,

Thank you for your answer, but it's not applicable on our printer :

Model : HP LaserJet 600 M601, HP LaserJet M604 PCL 6, HP LaserJet P4014

We don't use email and wifi.

Thank you

Hello TreeFrog,

Thank you for your answer. 

We think also it is probably that.

But do you know How can we tell the printer to refuse these impressions?

We have also Canon Printer and they don't have any print job from Guest 😕

Thank you,

Hi there,

Must of the time when someone connect his personal PC on any active directory environment and send a document to be print it will be register as a guess account because that PC does not have a valid user account on your active directory.

I hope this help.

Hello The Quan,

I think it can be a probability, but there is nobody at 1:021AM, 3:45 AM (The Hour is always in the night between 11:00PM and 05:00AM )

I Think the answer gets close to the print job.

We are looking after the guilty.

Thank You 🙂
