BARCODE FORMAT COMMAND EXAMPLE

The example below shows the barcode format command for a 3/4-in. high UPC-E barcode symbol with no human readable line. Default values are used for narrow and wide bar and space widths. The last parameter, intercharacter gap, does not affect UPC-E barcode symbols but must be sent with the other parameters. The command could be sent with the following program:

LPRINT CHR$(1);"AzM";CHR$(14);CHR$(0);CHR$(0);

LPRINT CHR$(1);CHR$(3);CHR$(1);CHR$(3);CHR$(1);
