62Chapter 4Selecting BarcodesCode V supports Version 1 and Version 2 Barcode commands. Version 1commands allow more flexibility in the placement of the human-readable textportion of a barcode. Version 2 commands have the advantage of includingthe name of the barcode style in the command. Either command must becontained within a valid Graphics Pass for it to be recognized by the printer.The Version 1 command allows the barcodes to be printed in two orientations:1. Horizontal2. Vertical (rotated 90 degrees clockwise from horizontal).The orientation of a Version 1 barcode is independent of the orientation of theGraphics Pass it is in.The orientation of Version 2 barcode is the same as the Graphics Pass inwhich it appears. Thus, Version 2 barcodes may be printed in any of the fourGraphics orientations.Regardless of the command style used, all Barcode commands must occurwithin a Graphics Pass.Barcode DensityA control panel option (Darkbar) defines the Barcode density. If set to ON, thedensity will be high. The default setting of this option is OFF.Barcode HeightThe overall height of a barcode is determined by the window height (when thebarcode is horizontal or upside down) or width (when the barcode is verticalright or vertical left) as specified in the ^M sequence that precedes theBarcode Command Sequence. Human-readable characters are included inthe overall barcode height.The height range is:• 02 to 99 (0.2 to 9.9 inches) without human-readable characters (HRC).• 03 to 99 (0.3 to 9.9 inches) with human-readable characters (HRC).Character sizes less than 02 or 03 will cause the barcode height to assumethe minimum value (i.e., 0.2 inches without HRC and 0.3 inches with HRC).Barcode WidthThe width of a barcode is a function of the number of data characters to beencoded, the style of barcode, and the bar/space ratios.
