If you have a Hewlett-Packard all-in-one (AIO) printer, and you're having trouble getting some of its scanning features to work, take heart. HP's printing software offers a collection of settings that will likely provide the solution. The only problem is that HP keeps these settings so hidden that even some of their tech support employees don't know about them.I first became aware of these settings when I was unable to resolve a scanning failure with my Hewlett-Packard OfficeJet 8600 Pro. I had no trouble initiating a scan from software on my Mac. In fact, there are multiple ways to do this. HP's printer software includes two separate scanning utilities, Scanner and HP Scan. The former is accessed from the printer's Print Queue or the Print & Scan System Preferences pane; the latter is found in the Applications folder. Additionally, OS X provides Image Capture. These all get the job done.However, I was more interested in initiating scans from the printer itself. Doing this comes in handy
