Hi OdyX,

I don't have another printer readily available - I'll ask around.

By any other way I meant printing from locally running programs or from another Computer.

As you think the PPD might be at fault I tried configuring the printer as a Generic Postscript Printer using the POSTSCRI.PPD.
I'll try to find something that works better.

The CUPS Printer Test Page is printed just fine and double sided.

IOS on the other hand causes the printer to print an Error after flipping the paper:

ERROR:

This makes me think either the printer itself or the PPD files are at fault
here. Does the same happen on other printers that you could eventually test?

What "any other way" are you referring to here? Duplex-printing from non-iOS
devices?

That's a reasonable expectation indeed.
