How modern and digital we still are, there are still times when we need or want things on paper. There may be contracts to sign under which there is no digital signature, photos of the children to be sent to grandparents, or maybe an invitation to something.
Instead of getting around the computer, It's easy to print directly from the Iphone or Ipad, and it's almost always possible to arrange more or less easily.
With Airprint Printer
Many modern printers have built-in support for Apple's AirPrint technology. This means that it appears in the iOS print window without any other controls.
If you have an older (or even) very simple) printers that can only be connected via USB, you can not print directly, but by installing an application on your computer, it can bypass that shortcoming.
If you have a Mac and a printer connected directly to your computer or network, for example, in the usb connector at an Airport Base Station or Time Capsule, there are two programs to choose from: Printopia (about $ 170) and HandPrint a "donation" of at least 40 kronor).
Printopia is simpler of both. All you have to do is check the printers you want to share with Airprint. It works with local (connected directly to the Mac) and network printers. Because IOS Print dialogs barely have any settings at all, Printopia has added it instead, so you can choose paper quality, size, and anything else you can customize on the printer. In other words, it may be more flexible than printing directly to an Airprint printer.
For Windows, there is a similar solution in the O'Print program.
