Hello Ingebjorg, and welcome to the HP Forums.
I see you are looking into scan options. Due to the age of the printer, there is no HP software available.
I would recommend following this document on OS X v10.9 Mavericks: Installing and Using the Printer on a Mac, particularly the section on 'How do I scan with the driver from Apple Software Update?'
Please let me know if you have any questions. Thanks for posting on the HP Forums.
