Hi all
I am working on a web application project where barcode is generated as an image and printed on the label printer.The label printer is datamax printer.But the problem is when the barcode is printed on a normal printer in an A4 sheet the scan is successful.But when printed on label we couldn't scan.Can anyone help for this issue.And also i want to know how to use barcode metrics.Will it solve the problem?am using barcdoe128.
