I started using Inkscpe this evening, all the settings were the default ones.

I tried printing: a black page came out of my printer (see a pdf version on the right of the screenshot). I thought the transparent background may have fucked things up so I setted it up to white: I got another black page out of the printer.




I'd really apprecite to be able to print it properly

You might try saving a copy as PDF and viewing/printing that pdf. Works well at times.

Nice tip, it works

If someone has another solution allowing to print from inkscape, I'm still open.
