Anyway, if you search the web for drivers for a particular printer other sites will seemingly offer what you're looking for by way of "driver update" applications. I tried one of those thinking it would do the job for my particular driver. Well, it seemed to check every driver known to man. Maybe they do identify drivers that could be updated. I don't know. However, they do want you to register to get a password that actually enables said updating but I skipped that. Wisely, I think. The software deposits spyware being the point here, so stick to the manufacturer's site for drivers if possible.
The printer is a Konica-Minolta and the KM site was terrible. However, a previous color laser printer I bought from them gave good service and tech support was excellent. A newer printer will probably not be such a hassle to find downloads for on their site and you'll have the installation disk anyway, most likely. Good printers. Web site deficient.
