Wow, I just spent an hour troubleshooting only to realize the problem was not printer ink or settings so much as the IRS PDF file which was not printing for me.

I got it to work by printing in standard and in a smaller screen view.    So…if you have this problem I recommend first try to print a text file – if that fails you may have ink or other problems, but if it’s a PDF try messing with the printer quality settings (use standard first) and the view settings.
