ABSTRACT:
The laser beam printer apparatus can superimpose adding printing data, which is different from printing data, on printing data after bit map image data is expanded to printing data or while bit map image data is expanding. Adding printing data is synthesized with printing data at a predetermined period on basis of a clock supplied from either a main controlling unit or an image forming control section. Therefore, new printing data such as symbols and marks can be simultaneously outputted without newly remaking printing data.
