What's free hasn't changed: finding your printer, diagnosing what's wrong, reconnecting it and printing a real test page — unlimited, on as many printers as you like. This update brings everything else in line with what Pro has always included: your printers in the iPhone's Print dialog, a saved library of printers to switch between, iCloud sync, automatic recovery, Wi-Fi Direct rescue and Wake-on-LAN. If you were using one of these without Pro, PrinterHealer now tells you which feature it is rather than quietly doing nothing. Have a printer we should support better? Email [email protected].
