I have used DYMO Web Service Beta Installer Beta 2 to print labels from my web app to a dymo label printer.
With the initial page load of the print module it works perfectly. But when I go to another webpage then go back to the print module or refreshing the webpage I get this error when I try to print again. Link to image
I have updated my dymo's software driver hoping that it would fix this issue but it did not.
EDIT: updated links
Just found the source of the problem: article. I TLS 1.3 and it works. I hope they would fix their framework soon.
