To print narrow barcodes with DevExpress, do the following:
– create your report
– add a XrBarcode report control to the report and configure it (bind it to fields, choose symbology, configure symbology)
At this point, if you try to have a small width for the field, it is very likely the control will print an error text like ‘control bounds’.
Do the following:
– verify the symbology (for example, if using code 128 and displaying only digits, use Charset C)
– set the report measuring units to TenthsOfAMillimeter
– set the XrBarcode Modulo value to 2; if you try to make it smaller, the barcode will not be readable.
