I have been using my SD3 for the past year with no issue nothing new was recently installed but when I went to print to day I get this message  "the port 'com3' does not exist"
com 3 is not listed in my device manager or in my MB bios. I tried to add hardware in windows and when I try  to add a com3 it stated that it is in use (still not listed in device manager though) Could this be a issue with my computers Mother board?
