Hi all,
after a long time investigating in the issue that a step with a QR code (via web widget and googleapi.com) can not printed, i found out, that the webpage widget can not handle the generated QR code picture from googleapi.com and the printing routine from the tulip player hangs.
When i replace the webpage widget with a sql connector function to generate the QR code, tulip can print the step without any problem.
To reproduce this issue add the webpage widget with the fixed URL:
https://chart.googleapis.com/chart?chs=150x150&cht=qr&chl=test
add a button with the trigger “print steps: this step”
run the player: the QR code appears
click the print button and select a printer from the list (i tested it with PDF and physical printers)
=>
the print out hangs, no PDF will be created; you have to crash the player
this is reproducable on different stations and computers.
So: why can not print the player the googleapi result? What is the player waiting for?
this phenomenon cost me a lot of time and gray hair 
Regards Chris
