I’ve participated at this contest organized by Ricoh Europe. It was the first european contest in the embed market. The goal was to develop an embedded application for one of Ricoh’s Printer/Copier/Fax. It wasn’t MIDP, but a CDC+FP profile with some extra. I’ve won the university contest in the “Business” category with my application MadaPrint.
It is a document repository that run on a Aficio Java-Enabled printer. With MadaPrint is possible to share documents and print other’s. It is managed by a web interface that run on tomcat 3 (the machine has an ethernet interface) and a java Xlet that run on the printer’s LCD.
This experience in the embed world was really interesting, hope will be another contest next year.
You can download the source code and jar here and the presentation document of MadaPrint.
Oh, it is released under the GPL.
