The document summarizes the results of a usability test conducted on the Xerox PrintBack mobile printing solution. 6 participants tested the setup and installation of PrintBack on various phone and computer platforms. The test aimed to evaluate the installation process and printing/saving functionality. Results found the mobile app installation was easy but the computer version needed clarification. Feedback suggested making the download easier to find on websites and clarifying steps after installation. In general, saving documents and printing from mobile were difficult to use. Recommendations included simplifying language, explaining saving benefits, and improving system feedback and status visibility across devices.

27. MOBILE FEEDBACK
users Do you have any suggestions for the future of this system?
User 2 Once I realized that the app was not already downloaded, I downloaded it from the
app store it became very easy to install and use.
User 5 I like it. It didn't seem as complicated as some apps I've worked with... I guess it was
so easy that I thought I must have missed something.
User 6 Not sure how I link it to my printer exactly...
I wish that was more explicit

30. COMPUTER FEEDBACK
users Do you have any suggestions for the future of this system?
User 1 Make the download easier to find.
User 2 I was a little confused what to do once you installed the program.
User 3 On the page that talked about PrintBack drivers and installers a bolded download
PrintBack link perhaps.
User 4 Couldn't find the xerox PrintBack download button without having to search for it on
the site. A few questions I was unsure of the answers to make the correct selections.
User 5 If the program could install right to my application folder... or give me a save as function.
User 6
The link to the download page was not working, therefore I could not complete the full
task. It was very easy to find the download, but the link to download it was broken.
Hence, I don't know that I can answer most of this survey meaningfully.
