I just got a Macbook pro and a HP All-In-One PhotoSmart c3180 printer. I tried to set it up with the following steps. Step 1: Install drivers on mac, connect to mac, test. No problems Step 2: Install drivers on PC desktop, connect to PC, test. No problems Step 3: Share the printer that's connected via USB to the PC. No problems Step 4: Add networked printer to printer list on mac. Found on network. No problems. Step 5: Attempted to print apples webpage from the mac. 375 pages of junk. My conclusion: Driver error; i installed and tested with the mac wired in, so i assume the problem was when i added the printer. I backstepped and saw that the printer was added as "Generic PostScript Printer". I went to change this and the first option is "manufacturer". HP; piece of cake. But my printer isn't on the list; in fact, nothing even similar to my printer is on the llist. Apple told me "it's HP's fault call them". HP told me "it's not possible, give up". So how do i get my printer on the list, and can this even be done? P.S. it's a wireless network.
