If drivers for your printer do not show up in Snow Leopard, and there is no option for a generic driver (that you can use until original ones arrive), then you might be in luck if you've got your Leopard disc handy. Insert your Leopard disc, and then click on Optional Installs. Then in the next window you might have to click on Optional Installs again. From the new Window, select Printer drivers. Select the appropriate brand, and then install. So really, we're trying to use Leopard drivers here, moved from your Leopard disc onto Snow Leopard. If you're in luck, usable drivers might show up in your System Preferences, or perhaps a generic driver that will work. Best of luck!
