I am considering getting an all-in-one from the WF Pro line, probably the WP-4530 or WP-4540. We need one for our small office to replace our HP 8600A which we liked but it keeps freezing up, and we have to turn it off and on to get it to work. The new one will be used mostly for office tasks, but I was wondering if the print quality was acceptable for the occasional photo we would need to print. I also see a few offerings on-line for refillable carts and was looking for any experiences or recommendations on these. Thanks
