System for controlling the printing of electronic documents with various page description languages and other parameters

A system for transferring printing jobs comprising digital image data from a user through a line to an electronic printer for execution therein, the line having associated therewith a context comprising a program parameter relating to processing of the digital image data by the printer, comprising:

• processor means operatively associated with the line for translating a printing job having a preselected context into a form understandable by the electronic printer, having associated therewith a set of selectable memory maps, each memory map having a sequence of instructions to translate a printing job;
• persistency means, associated with the line, for retaining the context of a printing job transferred through the line and causing the processor means to translate a subsequent printing job passing through the line according to the retained context;
• and
• state selection means, associated with the line, for preventing the persistency means associated with the line from retaining the context of a printing job after the processor means translates the printing job;
• the state selection means being sensitive to a "sanitary job" instruction included as part of a printing job, the state selection means preventing the persistency means associated with the line from retaining the context of a printing job having a "sanitary job" instruction associated therewith, the state selection means being adapted to reboot the processor means in response to the "sanitary job" instruction.
