PrintStressTest

PrintStressTest is an InternalUI app which is used to run various tests on printers, as well as the iOS devices used to send documents to the printers. Inside the app, there are various images and PDF documents that you can send to any AirPrint compatible printer. You can also select multiple to send at one time. Many of the images within the app appear to have been taken by Apple engineers, as they are all located around the San Francisco area. There is also the option to run a Bonjour Resolve Test, which seems to collect data from the printer. The PrintStressTest icon actually contains a humorous reference to a scene from the 1999 movie Office Space, in which Samir Nagheenanajar and two fellow Initech co-workers get so frustrated with the printer, which is always giving them errors, that they take it to a field in the middle of nowhere and proceed to completely wreck it.
