Gutenprint works purely with bitmap data. If the source material is not 
an image then something else has to convert it before it's handed to 
gutenprint.

That "something else" can be the application itself, the framework it's 
using to print stuff, or a filter in the CUPS processing chain (eg 
"pdftoraster").  Since you're seeing wonky fonts, it could be any of 
those layers -- the application (or framework) could be inserting bad 
font data, or the rasterizer could be mis-interpreting said font data.

But either way, by the time Gutenprint is handed the print data, it's 
already been converted to a bitmap.
