Most printers have a sticker that shows:

Quick Tips

• Write down the full model name (e.g., HP DeskJet 4155e or HP LaserJet Pro MFP M428fdw).

• When downloading drivers, enter the exact model name on 123.hp.com or support.hp.com.

• The product number (like 1KR54A) is useful if the full model name is not clear.
