Disclosed is a system (700) for printing a page description comprising a set of instructions, conforming to an interface, to draw at least one object on a page. The system comprises a filter module (705) for simplifying the set of instructions to an output set of instructions that is a subset of the interface, and an output device (711) for printing said output set of instructions. The system also has a set of thresholds (915) and flags (913) controlling the method by which the filter module simplifies said set of instructions, the flags and thresholds being dependent on the capabilities of the output device.
