A printer has a controller configured to receive one or more printerlets and data from one or more computers connected thereto. Each printerlet includes one or more computer configuration instructions and the controller invokes each printer configuration instruction received in a printerlet. A memory connected to the controller stores therein a plurality of object oriented classes each configured to control at least one operation of the printer. A print engine connected to the controller to be controlled thereby prints data on print media as a function of at least one object oriented class invoked by the controller from the memory in response to the controller invoking at least one printer configuration instruction.
