Updating View While PrintOperation is Running

I am desperately trying to update a view for printing while the PrintPanel is open.

Situation is as follows:

We have a POS system where clients will have ticket printers and regular printers connected. When a user starts a print operation and selects a ticket printer I want to load another template for the print job with special layout for the ticket printer. Same vice versa.

I am able to detect the printer switch and where it switches to, so that's fine. But whenever I alter the view contents with the new template and click print, the print output did not reflect the changes. I tried a few things.

- Redrawing the view (works on the display) and setNeedsDisplay
- Replacing the current printoperation with a view with other content
- Removing the printoperation context and regenerating (destroyContext)

None of them did work.

Anyone got a hint?

Thanks! Koen@sofa
