myTaxExpress or T2Express don't print out tax form directly, instead, they generate a printable .PDF file for print. After the .PDF file is created, you can see its file path showing on the screen. Next, you need to run free software Adobe acrobat reader or Foxit reader to open the .PDF file, and select the pages you want to print.
In this case, after .PDF file is created, you can copy the file in a USB drive; then bring the file to another computer where a printer is attached. Finally you run Adobe reader or Foxit reader in that computer to open the .PDF file and print.
