Ken Hamady has a blog reviewing alternatives for adding QR Codes to Crystal reports: kenhamady.com/.../2342

I have question here about licences of barcode fonts - does it consumes one user licence (on server) or seperate license for each user is needed?

Disclosure: I'm the developer of CUT Light (the UFL solution discussed at the end of Ken Hamady's blog). 

I can't comment on the licensing for other solutions but, for CUT Light, there is no need for special fonts. And licensing is per machine. So 1 server = 1 license.  

Hi,

Considering this was the first result I get when I search for QR code Crystal Report for Sage X3, I will be putting in some details from a year+ of research.

Make sure to test the print from Sage X3, not from Crystal Report's preview. Do note that Sage X3 uses its own Crystal Report engine and generate report on-demand.

1. Using Crystal Report for Enterprise from Crystal Server license: No. Ref:https://www.sagecity.com/us/sage_x3/f/general-discussion/185045/sage-x3-v12p26-print-server-error-when-printing-reports-created-from-crystal-reports-for-enterprise-when-testing-for-future-qr-code-purpose/502976#502976

2. Using Crystal Report's User-Defined module and special fonts (such as BarCodeSoft): No. Ref: https://www.sagecity.com/us/sage_x3/f/general-discussion/202610/print-engine-error-in-sage-x3

3. Host a QR code generator server. At Crystal Report, apply a dummy image and dynamically replace that image to QR Code equivalent: OK. Check with your development team to host the QR code generator server.

I have not tried CUT Light so if anyone tested and tried printing in Sage X3 successfully, I would be interested in the answer.

Additionally, please skip patch level of Sage X3 v12p34 as there is a known issue with it:  [v12p34] Unable to print Crystal Report dynamic image pulled from HTTP on a HTTPS website
