BEWARE! DON'T SIGN UP FOR THE "FREE" TRIAL! IDK if this app works or how well it works, but I DO know that you apparently can't cancel the "free" trial, and that Grigoriy will steal your money. This app could not find any printers. I don't know whether the fault was in the app or in my printer setup. Either way, I had no use for it that day. I emailed a subscription cancellation request (via the app's "Write to Us" option) THE SAME DAY - well within the 3-day trial period. I never received a reply. I emailed a second time - AFTER my account had been charged $9.99! - and I STILL have not received a reply. STILL WAITING, Grigoriy...😠😔😫
