It will save me a lot of work back when I used to scan to a USB drive, switch it to my computer, and search HP_Scan directory and hope my document appeared. After a few seconds, the application will create a PDF file in the same. You may either drop a PCL, PXL, or PRN file on to the application icon, or launch the application and select a PCL, PXL, or PRN file from a standard file listing. Thanks HP for a great, AND FREE, scan App. The Windows and OS X/macOS versions work in almost identical ways. I went to my computer' scan folder and there each document had been saved to a separate jpeg. Delighted, I stacked several documents on my printers from feed and each document was scanned.
The Easy Scan App reappeared and when the scan completed and displayed in the App, I clicked on 'Send' which opened a save window where I selected a Folder for storing all future scans.
Once completed, a document that I had previously placed on my printer started being scanned. I downloaded HP Easy Scan to my new iMac Pro and once the download completed and the App opened, I went to devices on my computer and clicked on my office 'HP OfficeJet Pro 8600' Icon - immediately my computer started downloading a new print driver file.
