That looks like a third party extension. You are using a printer queue? Did you correctly uninstall the old printer driver and set up the new one in your system and in the printer queue?
Yes, could be third party. I have installed a new printer, that uses queues. There was no old printer driver as it's a totally new one.
After the error message, I'm able to get in Illustrator and also send a print to the new printer. Just not sure what that error is and what impact it could have.
Illustrator has some issues with printer queues.
What you might try is install and set up a PDF printer as your default printer.
