Share your printer
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 running OS X v10.4 or later.
Printer sharing is for non-network or non-wireless printers that typically are 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.
Choose Apple menu > System Preferences, click Sharing, then select the Printer Sharing checkbox.
Below Printers, select the printer you want to share.
When you share a printer, all users on your network (“Everyone”) can use it by default. If you want to restrict access to specific people, continue with steps 3 and 4.
Click the Add button at the bottom of the Users list, then do any of the following:
Select a user from Users & Groups, which includes all the users of your Mac.
Select a user from Network Users or Network Groups, which includes everyone on your network.
Select a person from your contacts. Create a password for the person, then click Create Account.
When you add people to the Users list, access to the shared printer is reset to No Access for users on your network (“Everyone”). To provide access to Everyone again, click the triangles, then choose Can Print.
To remove a user, select the name, then click the Remove button . You can’t remove Everyone.
