Over the past few days, Apple has been releasing updates for printer and scanner drivers in Snow Leopard, iSight cameras in LED Cinema Displays and QuickTime 7 for Windows.
First, Apple released printer driver updates for Snow Leopard for Lexmark printers and Brother, Canon and HP printers and scanners.
Next, Apple released a firmware update for the iSight camera that's built into the Apple LED Cinema Display. According to Apple, this firmware update corrects an issue with the built-in iSight camera on the LED Cinema Display where the camera may not be recognized by applications.
Finally, Apple released QuickTime 7.6.5 for Windows, which fixes an issue where applications weren't reliably loading libraries required by QuickTime at startup and the incorrect display of QuickTime movies embedded in a webpage using custom scale attributes.
All of these updates are available from the Apple Support downloads page and Software Update.
