1. A computer implemented method for generating a plurality of bit maps suitable for high-speed printing comprising the steps of:

  • (a) generating a page description code specification, the page description code specification defining at least one data area to become variable, and the page description code further defining a graphics state corresponding to the data area, the graphics state including at least one attribute which controls the appearance of data in the data area;

    (b) interpreting the page description code specification, and during the interpretation, identifying the data area defined by the page description code specification;

    (c) storing the graphics state corresponding to the data area upon the identification of the variable data area in step (b);

    (d) retrieving a variable data item from a plurality of variable data items;

    (e) applying the stored graphics state to the variable data item to generate a variable data bit map; and

    (f) repeating steps (d) and (e) for remaining variable data items in the plurality of variable data items, whereby the stored graphics state is applied repeatedly to generate a plurality of variable data bit maps.
