I purchased a Dymo Twin Turbo to print shipping labels for my business. It printed for a day or two, but even then not well, with a printer error message after each label. Now it won't print at all and all I get is a printer error message. I've tried re-installing, I've tried changing the printer port, the printer driver, etc., and nothing seems to work. Any suggestions?
