I am having problems getting my Macbook Pro to send print jobs to an HP Colorsmart C4180 printer which is connected to a Windows PC on my network. When I tried to add this printer to my list of printers, I couldn't find the correct model in the printer utility's list of HP printers. I tried installing the printer's software on my Macbook Pro from the HP driver disk but still couldn't get the printer utility to see the right driver. The printer utility did have an entry for an older HP Colorsmart printer, so I used that instead. It seems to work okay, but I am annoyed that I have the right driver available to me but the computer won't use it. What did I do wrong?
