Every time I launch Mathematica 10.1, I am bothered by the following error message:

 ![2274Untitled-1.png](https://global.discourse-cdn.com/wolfram/original/2X/6/68e9f6f4384c4c47946a1ed81364c46444f22756.png)

Maybe someone wants to know…  
This wasn’t the case initially, when I installed the product.

That’s interesting.This looks like a really old issue with either Mathematica 8 or 7. The culprit involved a bad printer driver for certain printers - often label printers.

Does anythign strange happen when you evaluate SystemInformation[“Devices”]?

[Wolfram Technical Support](https://www.wolfram.com/support/contact/) are the most likely people to have run accross this issue with version 10. I would contact them. It will probably help if they know

- The output of SystemInformation[] contained in a notebook
- Which printers if any do you have installed on your machine.

I remember in the past, this was fixed quickest by installing a new printer driver for certain people.

The problem seems to have been with my default printer indeed.

Last week, I have received an e-mail from the student organisation responsible for the printers, saying that we should install the new driver since the old one is no longer valid.  
I suspected then that the problem is related, however after I’ve installed the new driver, the error persisted.

I had to change my default printer, in order to get it run unpretentiously.

Thank you, Sean.
