all points addressable (graphics) (APA)
All Points Addressable(APA) states that all pixels of a computer graphic, a display or the print points of a printer can be addressed and changed individually. The APA mode assumes a pixel-oriented display and has the advantage that you can change the pixels of a graphic individually and do not have to change the entire display.
When printing barcodes, the APA mode is important because all points of the barcode can be set individually.
