I think you can leave the scanner out of the argument.
Something is out of joint either with the parameters of the saved file or the printer's software.
Assuming you don't have an "out of ink" problem check the size and saved format of the file.
Again: Has anything else been changed recently?
If its not the file, and not an ink problem you may have to re-install the printer drivers, but do check that it will print Windows testpage first.
