Looked into the permissions issue. On running the verification test, the report indicated the same group problem as
Harv pointed out. Should be gid 26, is gid 0...etc. I figured that if it brakes my printer, I'll just do as Harv or I'll create a group with the ID of 26 in Net Info ...blah, blah...whatever.
So I run
Repair Permissions anyway. The USB Epson CX5200 is connected to my G4 tower running OS X 10.2.8, USB File Sharing is on in both systems, all connected wirelessly with a D-Link router. To my amazement, the printer worked with the new permissions and over the WiFi LAN.
Harv, I don't know what to tell you at this time, don't know enough about this yet.
What's your exact set up?
