Your thread says HP scanner prints with a blue tint but the body of your post talks about the printer. It is possible that the scanner has "bloom" under the glass or on the mirror. I submitted a post here a couple of weeks ago on scanner cleaning click here and I notice someone else posted a link from within a post yesterday click here It is also just possible that it is the photos themselves. I worked on colour copiers for a while and it was known that some photographic processes used a bluish tint to enhance the photo's characteristics. Try using a photo from a different batch to ascertain whether it is the photos or the scanner. Also scanning a white A4 sheet and looking at it in your graphics package may help to determine if its the scanner. Running a test print on the printer may help to determine if it's the printer. Hope this helps.
