Can anyone point to a document that describes how to print from a Mac OS X 10.5.8 to an HP Photosmart C3180 series print connected to Windows 7. I can’t get anything but nonsense to print. I was able to do this with Windows XP, could not do it with Vista and am now hoping to get it done with System 7. HP has been no help at all. Apparently nobody who works for them knows anything about both computers.
Chances are, you won't be able to get it to work...
The specifications make me believe that this is a "dumb" printer. In otherwords, there is no significant processing power on the printer, it's all in the Windows driver. (Your computer does all the processing needed for the printing)
Network printing, requires the client system to have the driver for the printer, and thus there is no Macintosh driver... Thus your gibberish on the output.
Now, the only sensible option might be Gutenprint ( http://gutenprint.sourceforge.net). They do have drivers created for some of the photosmart models...
So one of those might give you a potentially workable driver...
