In regards to accurate scaling when using QR codes, I know it’s important to account for the width of the code and the printed paper when setting the code position. but since the generated code is in A4 size and the US only prints in letter size there is going to be some size difference when printing, is there a way around this problem ? my current solution has only been to fit the A4 size Qr code in a letter-size format using Illustrator, import it to jpeg then print?
We are aware of this limitation and are planning to add a paper size selection to the QR code generating command (along with a few other improvements). This should be included in an upcoming release.
