Yes, it is a PDF. I just meant postscript for the type of graphic. Sorry for my this misinformation. I am not such an expert for bug tracking or bug reports. What i found out additionally is, that apparently i am printing with:
IPP Version: 1.1 2.0
Airprint-1.7
So apparently its just my fault and i am doing something wrong. Just ignore it, if you can’t reprodruce it. Thanks
