I want to print the Massachusetts resident income tax return form which has both black and red letters. When I print this document with Adobe Reader or Foxit, everything is black and white (no color). When I print exactly the same document with Sumatra PDF, it prints correctly with red letters. Why would Sumatra PDF print the document correctly, but the other two do not? Note that I use both Foxit and Adobe Reader to print color documents all the time. It is only the tax form that seems to have a problem.
