Programming Overview
parameter specifies whether a fixed amount of data will be sent or whether delimiters will be used. In either case, the data sent must match the parameter setting. If a fixed number of characters are specified, then the exact number of characters specified must be sent. If delimiters are indicated, then matching characters must be sent before and after the barcode data to specify the beginning and end of the data. If an incorrect number of characters or delimiters are sent, the printer will not print correctly.
Barcodes that are too long to fit within the printable area of a label are truncated or do not print at all. This usually results in an unreadable barcode being printed. To correct this condition, you must set a narrower ratio, encode fewer digits, or use a more compact symbology.
Graphic Objects
Graphic objects are created by the landscape mode graphics command (GS *).
Graphic objects may only be printed as part of a landscape page. To print a graphic without entering landscape mode, you must use raster mode graphic commands.
No landscape graphic may be wider than 256 dots; however, a graphic may be as tall as the width of the LabelWriter printer's print head. If you need to print a graphic wider than 256 dots, you must either subdivide it into narrower sections or print it using raster mode graphics commands.
For more information about landscape graphic objects, see the descriptions of the graphics commands in this manual.

Line Objects
Line objects are created using the draw line in landscape mode command (GS l).
Line objects may only be printed as part of a landscape page. If the length of a line object is set to exceed the printable area of a label, the line will be truncated at the end of the printable area.
