PC 1 (Windows 7) is USB connected to a printer and is in the homegroup.
PC 2 (Windows 8) is in the homegroup, and the printer is visible when I click print.
Both PCs have Norton Internet Security.
Both PCs are awake, and the printer is on.
Both PCs have Network discovery, File and Printer Sharing, and Allow Windows to Manage Homegroup Connections on.
When I try to print from PC 2, I get no output and no visible error messages.
