Have MacBook Pro 2010. Love it. How to do? Can i possibly somehow or other connect my old warhorse of HP990 printer to it wirelessly? Anyway would be appreciated..
I assume that you have a HP DeskJet 990. In order to access this printer wirelessly, it can only be networked by connecting it to a print server. The print server must, in turn, be connected to a wireless router. The server may be a computer or it may be a dedicated server.
At any rate, your printer does not have manufacturer support past MacOS X 10.5.x. The HP DeskJet 990 does, however, have CUPS support by the Linux Foundation's OpenPrinting Project. Better yet, install Gutenprint which includes the HP DJ 990c driver as well as documentation for Apple's CUPS.
