After installing Snow Leopard and the HP printer drivers software update, the following warning message appeared:

The system extension “/System/Library/Extensions/CNQL1212_ClassicNotSeize.kext” was installed improperly and cannot be used. Please try reinstalling it, or contact the product’s vendor for an update.

According to this thread on the Apple discussion boards, CNQL1212_ClassicNotSeize is an old kernel extension for Canon printers that is no longer compatible with—or needed for—Mac OS X. Since deleting the file, I haven’t seen the warning message again.
