Hi Markellos,
The solution will depend on the printer you have. If you have a HP Officejet 5510 All-in-One Printer then take a look at this > The Printer Buttons Do Not Function in Windows 8 and/or this link. This second link explains how you can scan without HP Scan software.
If you have the HP Photosmart 5510 e-All-in-One Printer - B111a, you could use this document > A 'No computer found' Message Displays during Scanning.
If this resolves the issue please let me know. If you require additional assistance, let me know which printer model you have and if there are any error message when you try scanning. Thanks.
