2 weeks ago my laptop and desktop were both able to print from my brother 250c printer as they had for the past year. Today the printer printed blanks from my laptop(windows 8.1 system). I tried the same print on the desktop(vista os) and the printer was just fine. Went back to the laptop and message went to the printer, I heard the heads working but the pages were blank. Went back to the desktop and printer worked fine???????
