network printer HP 8730 Pro
With the newest version of Illustrator (is it 24) there comes a lot of trouble for users with HP printer - maybe all printer which are connecting over the local network. The issue is that Illustrator can´t open any ai file nore make a new files while the default printer is a network printer. Here it is the HP 8730 Pro. With the help of the support desk there is a workaround to fix this issue. You have to set your default printer to Adobe pdf. But this is not a real solution, it´s only a temporarely workaround. So hopefully it will fixed in the nearest future. In the meanwhile I go back to the previous version.

The problem is still existing. No proper solution in sight. Still working with version 23.0.6. Don´t know what developing is meaning at Adobe. New versions with new bugs that are not fixed. Poor performance.

I had the same issue, it actually works when local printer is working but we had some issue with local printer, it wasnt properly set up but it shouldnt stop illustrator from opening ai documents right ? Especially when i wasnt even trying to print anything.. hopefully it will be fixed soon..
