Installed gutenprint drivers, printer said something about problem during installation (or maybe it was software for the printer installed incorrectly), wanted to make changes and repairing permissions. Did it, nothing else happened. Printed one page, but printer refused to work, couldn't even shut down (button just burns green). Had to remove cable to force shut down. Works completely normal with Windows. Removed drivers, installed again, this time no asks about repairing permissions, but same thing. Kicked gutenprint out. Printer asking about repairing permissions means there was some error, but nothing serious or suspicious?
