I have a weird issue when printing QR Codes on CAB Squix 4M printer. Randomly happens that the QR Code size changes (will be bigger then normal).

Snippet of the label :

B 21.7,2.0,270,QRCODE,0.48;X-HM://0066F33LTBD61

The input is always the same number of characters 20.

Examples >

  1. X-HM://0066DW8YA0GX6 > normal size
  2. X-HM://0066F33LTBD61 > bigger than normal

Can anyone explain me the logic ?

  • There are different ways to generate a QR code from the same message - can you show the two particular codes which you get from these inputs (which are not necessarily the same codes I get now when I test it with another software)? – CherryDT Apr 26 '21 at 10:06
  • I you are willing to see the QR Code on images, I cant help you because there is a restriction on printer which is handling the issue when the barcode is too big and will not be printed. – LYR Apr 26 '21 at 10:11
  • I'd say the first QRcode leaves more room to being compressed by the algorithm than the other. Character count != qrcode size. Also error correction level has influence on that. Besides that; I've recently picked up Jscript and Im struggling to get it to work. I know this is an old post and I know this is now what answers are for but I simply cannot find any other help - That being said do you have any learning material or could summarize how you send the label to the printer (e.g. ftp, USB, what library used). – Core taxxe Feb 12 '23 at 18:27
