Cannot print on Android phone or Chrome with device toolbar

If I access https://printjs.crabbly.com/ from my Android Phone (Chrome) and try the first "Print PDF" example, nothing happens.
I only seem to encounter this problem with PDF files. I am able to print other types such as HTML or JPG.

It is possible to replicate the same bug if you enter the webpage in Chrome and toggle on the device toolbar.

I have tried to implement print-js (1.5.0) in a vue application and here I experience the same problems. Works fine on normal size chrome. All Firefox sizes and all Safari sizes.

Phone:
Samsung Galaxy S20
Android 11

If i look in the network tab I can see the following call:
