GRAPHIC POS PRINTER

摘要

POS printer software architecture for merging multiple graphical objects with standard printed data to improve the visual addition of content. The real-time merging of graphics with the legacy output POS printers begins with the receipt of legacy data into the printer buffer (14), active merge sources are retrieved, the merge source pixels are added into the raster data, the merge source counters are updated, a check is made to verify that all active merge sources have been added, and the raster line is sent to the printer for printing the combined legacy output and graphics.
