Hi HCSBHiggins,
I don't know about this particular model, but HP printers usually have that label in one of the following locations:
1) Rear cover or rear door
2) Inside (interior side) the front door or cartridge door
3) Behind the tray-2 (take out tray-2 and it's in the front of the printer)
I hope this will help,
Cheers!

Thanks to a post elsewhere, I found the serial number. Open the front cover (paper feed). Then press the button on the left side of the printer. It has a so called "universal" symbol. Then the serial number label was visible. Why did HP not include this critical info in their documentation or online "help"?
