CAE has retired Web Print in favor the new service Mobility Print. Mobility Print is an app that allows printing from mobile devices, similar to Web Print. Some of the advantages of Mobility Print include no restriction on file types (The only limitation is that which the printer supports) and the ability to print to any CAE lab printer or plotter.
