If your printer seems to be printing weird text and strange characters, it may be a driver problem inside your computer, not with your printer. Go to the manufacturer's site and download the most recent drivers for your printer, install them and then try to print again.
Follow the directions for installing your computer printer carefully. You may find that the printer does not work 100 percent correctly when you do not do this. Printer repair may be needed if you do not take the time to make the correct installation happen.
