I can only imagine how you feel having such problems... that would drive me absolutely crazy!

I use the "Print/Email PDF" function sometimes, when I have to email taxes and forms to clients, but I did not notice any unusual problems or delays. However, when I printed mailing labels in January of this year, after a while I was getting 'garbage'. The same thing has happened, on many occasions, while printing T2 returns. Thus, I print them to a PDF file first and then print the PDF file, just to be on the safe side.
