Q: my HP Officejet Pro L7580 is in a unreadible language and i'd like to know how to change it to english
A: Answer found posted elsewhere on Yahoo! Answers: "You need to turn on the printer and look for the help section on some part of HP. In my case, I opened Photosmart Premier, but yours will be different of course. Once you find the help section, type in language and do a search, make sure you click on list topics. I found mine here. and it runs you through on how to change it."
