Why are there three? Which one should be the default printer? Which one do I choose when printing under what circumstances? I believe that WS and XPS refer to specific drivers. When I check out Devices and Printers, the printer is listed three times: Canon MG5300 series Printer Canon MG5300 series Printer WS Canon MG5300 series Printer XPS These three choices also appear when I print anything. I've just installed the all-in-one Canon Pixma MG5320 (under Windows 7 64-bit).
