In the category called "Print all workspace QR-codes" you will find one field called "Page Size" and a button called "Print" (see image below).

 

Using the field called "Page Size" and the button called "Print", you can create QR codes for the workspaces available in the building you are working with. The QR codes will be collected in a pdf document. The pdf document in which the QR codes are collected can then be printed and saved on your computer.
