Share your printer on Mac
You can share your printer with another Mac or with a UNIX computer. The computers must be on the same local network as your Mac and the Mac users must be using OS X 10.4 or later.
Printer sharing is for non-network or non-wireless printers that are typically plugged in directly to your computer. You don’t need to share network, wireless or AirPrint compatible printers because they are already shared on your network.
On your Mac, choose Apple menu
in the sidebar, then click Sharing on the right. (You may need to scroll down.)Turn on Printer Sharing, then click the Info button
on the right.Below Printers, select the printer you want to share.
Do one of the following to choose who can use the printer:
Let everyone use the printer: Click the pop-up menu next to Everyone, then choose Can Print.
Choose who can use the printer: Click the Add button
at the bottom of the Users list, then select users.
Click Done.
To remove a user, select the name, then click the Remove button 
. You can’t remove Everyone.
