how do i write the network path?

If you have 'shared' a folder on your Mac to make it available for other devices i.e. your printer to access then you need to open System Preferences, then click on Sharing, then click on File Sharing.

Firstly this needs to be 'ticked' to enable File Sharing, and then you need to look at options and make sure SMB is also ticked and turned on. Then you need to look in the list of Shared folders and make sure the folder you want to use for the printer is listed there. If as an example the name of that folder is 'Scans' then the network path you want to use might look like the following.

\\192.168.1.11\Scans

(Change the IP address to match what is listed in the Sharing window on your Mac.)

Some printers however do things differently, they may have separate boxes for the address of the 'server', and for the name of the network share.

If you open Terminal, you can drag the folder to the Terminal window and the path to the folder will be automatically typed into the Terminal window.
