Precision 3660 suddenly started printing only part of a page.  Prints very little of any picture, more from pdf file, even more from Word. Sometime, if the printed page has not much text, prints the whole page.  Seems like PC is not able forward much information to the printer.  Printing from other PC or phone works fine.
