PrintToDevice vs PARM

PrintToDevice turns your iOS device into a virtual printer that allows you to print directly to your phone or tablet from your other devices. Simply open the app, find your unique printer name at the bottom of the screen and search for that device when adding a printer. Once the printer is added, you can print to it from any application as you normally would. The only difference being that the print goes direct to the device and not onto paper. If printing from another phone or tablet, simply select your printer from the list of printers when you go to print. There are no drivers to install and it should just work. Remember that your device and the device you are printing from must be on the same Wi-Fi network. If that's not possible you can always connect your devices together using your personal hotspot.
