Among Lexmark's "Smart MFP Ecosystem" range of Solutions, Lexmark Print Management is the app for tracking and managing user printing.
One of its features is print release. Print jobs can be run from a variety of devices to a generic print queue - and pulled from any compatible device on the network at the user's convenience, once they have authenticated themselves (card or password). They just select the document from their print queue.
LPM is the first software of its kind to be certified for AirPrint. This means it is even easier for Apple mobile device users to print. They print to the release queue managed by LPM in the same way as someone would from a workstation. This solves the issue which AirPrint users have in larger networks - finding the printer they want to print to.
