Scanning multiple pages on a HP Photosmart D110

[smileyheart5678]

I have a HP Photosmart D110 printer that scans and copies. My laptop is a HP Pavillion 360 with windos 10. I need to scan multiple pages into one document. I cannot find anywhere on the laptop screen or the printer that will let me choose multiple copies or add a page.  Does anyone know if this can be done? How do I scan multiple pages into one document.

If you are using the hp scan software, scan pdf document, and when the first page is in, click on the "+" sign to add more pages.

I am sorry but I do not know if I have HP scanning softwear. I am using the softwear that came on my HP computer so I thought I was. There is no + sign anywhere after i can my pdf. Not on my computer screen or on my printer/scanner. Where do I go to check what type of softwear I am using and how do I fix this?    Thank you
