You're right.
Being able to do a fix-scale print is an already-requested feature.
We're currently discussing porting the plugin to C++, and adding those bugfixes 
and feature while at it.
We'll need some more funding though (see the corresponding thread), and we're 
currently gathering support for mutualization. Please contact me directly if 
you are interested, and keep in touch on the list for news on that subject.
