What is the difference between Canon's iPF6300 & iPF6350 Printers

Both the Canon iPF6300 and iPF6350 printers are large format printers from Canon’s new line of imagePROGRAF printers release in January of 2010. Both printers are 24” and use the same new line of Canon LUCIA EX Inks. The main difference between the two printers being the built-in 80GB hard-drive that comes standard with the iPF6350, allowing the printer to save up to 500 print jobs and allows up to 25 password protected mailboxes. Having the on-board 80GB Hard Drive means the iPF6350 is better suited for production printing purposes.
