Completely useless

Ive used this app with some frustration through the past few years, but usually if patient enough, I could get my envelope to print correctly. I havent used the app in many months, tried it this morning and it wont let me print. Pressed the print button 30 times...nothing happens. This was never a problem before this. I still have the same printer, iPad, everything. Thanks for the worthless backwards update and I hope you thoroughly enjoyed my money I paid you for this soon deleted app...JACKASS!
