I didn't know about this until yesterday. If folks have ever felt daunted when they go to HP's driver web site to look up a given printer model, choose their macOS version only to find the only option is HP Easy Start, don't lose hope. Some folks (like me up until yesterday) would run Easy Start on their packaging machine, then grab the package that it downloads and push that out.
Yesterday, I found out HP offers the HP Easy Admin utility (https://support.hp.com/us-en/document/c06164609). It's a simple app, you drag and drop it to your admin machine, key in the HP model you are looking for and then it will allow you to download the actual PKGs you need to deploy with.
I try to keep up with new tools but didn't know that one existed until yesterday.
