Based on some screen shots posted at AppleInsider, it seems the Apple Online store will be accessible at the system level, offering to link consumable purchases directly from within the new Printer Setup Utility 4.0. The option, when selected, takes the user to the corresponding ink cartridge page within the Apple Online Store. This would eliminate the confusion of buying cartidges from the myriad of options for printers, narrowing the field to only products that worked with the user's particular model.
