I would need to print my slides. Could you explain the process in more detail than is written above?

Thanks, pressing Esc for Expose and printing the resulting page works fine in Chromium. In Firefox the resulting pdf has wrong colors.

It'd also be nice to be able to do this from the command line with chromium or chrome, for automation.

But when i try something like this:

chromium --temp-profile --headless --no-gpu --print-to-pdf presentation.pdf presentation.html

then chromium complains (and doesn't generate the pdf):

[1029/135902.727934:ERROR:headless_shell.cc(179)] Open multiple tabs is only supported when remote debugging is enabled.

I assume this has something to do with presenter mode's use of two windows, but i haven't diagnosed it further.

It doesn't open a second window by default tho. Must be something else causing the problem.
