Apple iOS

iOS devices (iPads, IPhones) use a common service, iPrint, which can print ONLY to devices made for or compatible with Apple's Air Print standard.

If you have such a printer, you are in business! Simply touch a JwC Print button and the iPrint screen will open, giving you a document preview and choice of Air Printer.

Don't have an Air Printer, but do have a Windows PC and some kind of printer (attached, wireless, print-to-PDF, etc.) it works with?

You might consider the following 3rd party utility which is in NO WAY associated with or even recommended by JwC.

However the author can state he has successfully used OPrint, available for short-term trial and at fairly low one-time cost.

OPrint enables your Windows computer to act as if it were an Air Print device, making available whichever printers you chose to allow iOS to send its print instructions.
