I feel obligated to give a shout-out to the qrcode LaTeX package at https://ctan.org/pkg/qrcode https://ctan.org/pkg/qrcode, written in pure LaTeX. Makes creating documents and templates with QR codes a breeze. Though, I'm sure most such printed documents are drafted using MS Word. :(
- dbaupp 5y agoNice! Having documents programmatically generating the codes from the underlying data is definitely much nicer and more editable than hard-coding static images (I say this even after writing the blog post that does ridiculous things with SVGs in order to avoid JS, ah well). For these particular posters, I suspect they’re generated in HTML/JS that the business can then print in their browser (or generated directly as a PDF, but I’ve seen some posters that have the classic printed-from-web-page header and footer with URL etc). There’s a lot of businesses in NSW/Australia, and all the posters are near identical. Thus, they wouldn’t be hand-crafted each time, and programmatically inserting a custom code into a word document would be a … surprising implementation decision (to me).
