Works well for me
Granted, I dont demand a lot of complexity from the app. It works really well to print out documents, webpages, etc. on the fly with my phone. I dont have much use for scanning via my iPhone & frankly I use my Windows based PC for scanning or creating pdf docs from jpgs, bursting & merging docs because the controls to scan or print in color vs grayscale & defining scan print & scan parameters are better in the Windows program on my PC vs on my iMac.
The only downside is sometimes I forget that you cant access the printer directly through the print routine. You have to direct the app to whatever you need to print.
For my use, it works great.
