I Bought HP J6057A I installed it with my system but it's not working. It is not showing anywhere in control pannel. Please help me in solving this issue.

What control panel? Be specific.
Also a nod to https://support.hp.com/us-en/document/bpj07429 about printing a sheet at the printer along with said update.

This sort of device does NOT plug and play. There are many steps to get it working on a network and some networks require steps that are not required on all networks. The skill level for this device is "advanced." Not only that the product is used so it could be a DOA so be sure to print the sheet of information per HP to see if the card even shows up.
