Stumbled across a very frustrating problem here: I imported the ttf fonts Casper Heavy SF, Casper Light SF, Casper Open SF and Casper SF. Although Inkscape displays the Italic style of the text where I choose Italic, it refuse to print this and print it as Normal.
Whatever I try it seems to be impossible for Inkscape to print them in Italic style. When I select Text and look into the Fonts Tab both CSS and Face show only 'Normal', 'Regular' and 'Bold'.
When I save the svg file as pdf it also shows the italic style text as normal style.
Is there a possibility to get the Italic style printed?

I hope that I am not being ignored by the forum?
In the meantime I figured out some workaround:
Selecting the text and then execute Object > Transform > Skew= -10
Gives the desired Italic style.
I hope someone will come up with a better idea.

I'd save a copy, then convert the text to paths before printing.
