Faxing from AC should give you exactly the same images and output as printing and faxing - what are you using to fax ? I have a print driver that is tied directly to my large fax/copier, but many people use Brother All in one Machines or the equivalent in another brand. I fax all my scrips, various orders, etc all day every day and never have a problems. If your images that you print are not as good as you want you need to adjust your settings on your twain driver - I think you need to be more specific about how you do each and then what exactly is happening.
