I have a umax 600x1200 dpi with 32bit's. I have been wanting to buy a better printer because mine is out dated. I am looking at a all in one with a flatbed 600x120048bit's. Is there a big deff between 32bit and a 48 bit scanner? It also can fax with the right software and the all in one is macosx compatible but i dont think there is a fax software for osx? can any one help?Does any1 fax anything under thanks
