I'm having problems installing the driver for my new HP Laserjet 1320 on Mac OS 9.1 (and HP don't help much by failing to provide a manual!). As instructed in the install procedure I opened the Desktop Printer Utility. I chose the USB option because I'm using a USB connection. I didn't know where to save the resulting file, so I saved it straight to my computer's desktop. When I open the Chooser, I don't see the printer listed. Is this because I saved the file in the wrong place? Help, please!
