I have a small desktop dell inspiron  model 3646 and ever since getting it last year my lexmark x2650 printer combo won't print  most of time until I reboot. It then works  a few times and then I have to reboot again and it prints again. I also get a message communication not available usb port. I have unplugged and plugged into another a port and get same results.It does this over and over.

I have updated the driver for printer to best of my ability and still same issue. The printer prints great so it is not printer.

Thanks so much!
