Printer drivers are available for download via Apple's Software Update for Mac® OS X running 10.6.8 and later. For all Laser and Inkjet multifunction printers, the ICA driver is also available for Mac OS X 10.6.8 and later. NOTE: MacOS 10.12 or macOS 10.13 drivers are compatible on macOS 10.14. As of now, there is no plan to release EC drivers. Mac OS X Jaguar Server 10.2.2 added journaling to HFS Plus, the native Macintosh file system, to add increased reliability and data recovery features. This was later added to the standard Mac OS X in version 10.3. To upgrade from OSX 10.5.8 (Leopard) to 10.6 (Snow Leopard), you’ll need a Snow Leopard install disk/usb drive or an installer on an external disk drive. To install the latest software updates on your Mac computer please follow these steps. Click on the Apple ( ) menu in the upper left hand corner and then select the Software Update menu option.
The App Store only shows updates for the OS you are using at the moment, in your case Yosemite 10.10.5.
If you want to go to another newer OS that is called an upgrade. This can be done through the App Store using the following link.
Mac Software Update 10.9
High Sierra is the last/ newest OS your Mac can use. Scroll down to Section 4 and click on Get macOS High Sierra.
Make a full back up of your Mac before upgrading.
Check to see with the developers of any third party apps you use that there are updates available so they will continue to work in the new OS. Another thing you need to check is if any printers/ scanners etc you use have updated drivers and software so they too can continue to function in the new OS.
