Is this compatible with a Dell Inspiron 1525 Windows Vista laptop?
Do I need anything special. Want also to print using Samsung Galaxy Tab 3. Does it fax and scan?
I don't think you need anything special for your laptop, as long as you have a wifi connection it should work, and you will be prompted upon installation to download the drivers needed to print from your laptop. It will print from the Samsung Galaxy Tab 3. You can either do the Google Cloud Print option or you can download an app called HP Print Service Plugin that is free from the Play store. It does not fax but it does scan so you can attach it in an e-mail and send your document that way.
