Hi @artron9,
Welcome to HP Forums, this is a great place to get support, find answers and tips.
Thank you for posting your query, I'll be more than glad to help you.
I understand that you wanted to know how to copy a photo which is 8x10 and reduce it to 4x6n or 5x7.
You can customize copy jobs using the Resize option in the Copy menu.
And here's the step by step guide for you in the link: Copying Documents or Photos
Let me know how this works.
You have a good day ahead.
