Yes. The full story is that the current version of AWRender cannot 
print indexed colour sprites (256 colours or less) while output is 
redirected to a sprite during printing. In order to print an irregular 
frame to a non-PostScript printer, OvationPro redirects output to a 
sprite internally, so this explains all of your findings above.

Mind you, the current version of AWRender does not really do a good 
job of printing indexed colour sprites anyway, so even in cases where 
it appears to work it prints them with degraded quality. AWRender 
still has the old ArtWorks 1.7 sprite printing code, which is pretty 
poor and which was used by ArtWorks until version 2.3. I have updated 
it significantly for ArtWorks 2.4, but this new code has not found its 
way into AWRender yet. I think the above problem will go away when I 
have ported that code across.

It really is a limitation in AWRender.
