Hi there,

I have tried to create a printer instance in cups by using comand sudo lpoptions -p Zebra_GLS/Zebra180 -o orientation-requested=6 to create an instance of Printer Zebra_GLS (printer name) called Zebra180, which has 180 degrees rotation of pdf to be printed by default as the main instance Zebra_GLS is printing upside down... At least neither the instance Zebra180 nor any other change shows up in the printing menu when going to print the selected pdf - e.g. in Acrobat Reader or any other software.

Can anybody help out here?

Did you try making changes to the currently configured instance of the printer in the CUPS web interface?

Make sure you have enabled the Web Interface for CUPS if you're on 10.14.
Open terminal and type sudo cupsctl WebInterface=yes followed by a return. Enter your admin password when prompted.

Then open your browser and type http://127.0.0.1:631/printers and press return.

It is solved:

Here the solution provided by the CUPS driver developer - thank you so much:

lpadmin -p printername -o orientation-requested-default=6
