I don't think this problem is to do with the cable as my F4180 prints slowly and also copies slowly. I have done a number of copies this evening and despite the fact that the printer was unplugged from the computer before pushing the copy button it still worked very slowly taking 5 minutes to do one A4 page. The black ink level warning light also came on and so I switched it off and back on again and the light went out and the printing speed was normal and much quicker than it was. This makes me suspect the internal memory that documents are sent to to be printed, perhaps the capacity is too low. I am not sure if the driver is to blame but having had a lot of slow printing it seems to have cured itself..Spooky...thoughts please
