Trouble browsing Windows network printers from Mac
Apple's knowledgebase article on troubleshooting shared Windows printers specifies that printers on a different subnet won't show up in the Windows dialog of Add Printer. This sounds to be the case for you.

Since you're able to connect to the domain via smb, you should be able to manually add the printer(s). Select the "Advanced" button at the top of the Add Printer dialog from your screenshot.

Select "Windows" from the Type dropdown menu. You can manually enter the printer's smb URL:

smb://Windows_name/printer_share_name 

or possibly 

smb://user:password@Windows_Computer_Name/Shared_Printer_Name

Select the appropriate driver and click "Add".
