Printing issue on network

Just wondering, is Printer Sharing enabled on the ones that can't Print?

If so disable & Reset the Printing system...

Reboot.

Sharing is not checked off on the remote printer.

Not sure I understand that. Say Computers A & B are Sharing the Printers connected to them with Computers C, D, E, F, & G...

Only A & B should have Ptinter Sharing enabled... & I think they'd need differently named Printers to not get confused,

Another test on one that cannot find the printer,,,

To find out if it's system wide or user specific, try this...

Open System Preferences>Users & Groups, unlock the lock, click on the little plus icon, make a new admin account, log out & into the new account.

Does it work in the new account?

Restarted the Printers & Routers yet?

Anything using a StaticIP?
