Printing is declining

I have no idea how the back-end systems work, but in Taiwan you can print documents at a 7-11 via email your documents to a special address, or upload them to a website, and it will respond with a QR code. Scan that QR code into the machine at any 7-11 store in Taiwan and print your documents. Or you can use a USB stick, but that is a pain compared with just uploading them. Since practically everyone here lives within a few feet of a 7-11 store it is basically impossible to justify buying a printer for personal use.
