Click on Start > Settings > Printers and Scanners, click on the printer that you have plugged in and click the "Manage" link .  Then click, "Printer properties." Select the "Sharing" tab at the top and click on the box by "Share this printer."  You can use the default name or change it in the "Share name:" box.  If you will be sharing the printer with multiple devices running a mixture of Windows (32 or 64 bit) then you should enable the "Render print jobs on client computers" option to ensure other users can easily install the printer when ...

The following list is different OS's that are currently in use for mobile phones: Android (Google) iOS (Apple) Bada (Samsung) Blackberry OS (Research in Motion) Windows OS (Microsoft) Symbian OS (Nokia) Tizen (Samsung)  This list is a little misleading; Samsung actually runs on Android OS and Tizen is an OS that is currently being used on Samsung Z Phones, smartwatches, cameras, and other Samsung smart devices like refrigerators.  Bada was discontinued in 2013 when it was merged wit...
