Common problems HP Solution Center not working : Adobe Flash Player Error and Unable to scan
We would like to share some of the most frequently asked questions about HP Solution Center not working : Adobe Flash Player Error and Unable to Scan.
HP Recommended
HP OfficeJet 4655 All-in-One Printer
macOS 12.0 Monterey

1.) How do I do double-sided scanning in HP Smart 17.11.1 for macOS 14.4.1 on an OfficeJet 4655 All-In-One Printer? I used to be able to do double-sided scanning in older versions of HP Smart but can't figure out how to do it in 17.11.1.

2.) How do I rotate a scan by degrees smaller than 90 degrees? I used to be able to rotate by 0.1 degrees under Crop (to straighten a slightly askew scan) but am no longer able to do so by degrees smaller than 90.
