Why aren't QR codes displayed in the preview or when I print the report?

Hello,

I'm creating a report in which I need to include a field containing a QR code image. I'm using a SQL Server database.

Something I've noticed is that when I first place the field in the detail view, the QR code displays in the preview, but when I switch to design view and then return to the preview view, the QR code no longer displays. If I print the report, the QR code also doesn't display.

What could be causing this? Can you help me?

I'm using Crystal Reports 2013, and the database contains 1,000,000 records.

I think I've found the reason why the QR code isn't displaying.

When I refresh the report data, the QR code appears again. I think because the number of records is so high and the QR files are in an image field, the report isn't able to display the images until the data is refreshed again.

I don't know if this is the real reason, but right now, every time I refresh the data, the QR codes appear again. This even happens when I send the report to the printer.

Hi, Are you using url to generate qr or straight using qr code from sap?
