Please add some info

[pcav]

on how the plugin works (in particular, where to find the new command once installed)

[manisandro]

Well it installs itself into the plugin toolbar with a intuitive printer-with-lightning-bolt icon and when you click on it you get a dialog with a help button, which opens the documentation. I recon that should suffice?

I have a lot of plugins installed, so it is difficult for me to find (yet another) icon; I guess it may be the same for other users. My suggestions:

• add a menu as project>instantprint
• add a note in the About telling the location of the new icon. Thanks.
