Hi Antione,
Just being curious,
How xpra handles client side printing !!!
For e.g when i connect to xpra server from windows xpra launcher(desktop client) , server shows windows client's local printer in its printer dialog box list and also prints it to clients selected printer correctly, all this done without having python 2.7 installed on that windows machine...
Also in server i saw all windows client printer listed in cups(i.e by command lpstat -v ) and after session disconnect clients printer are gone..
this is just awesome. How it is done !!!
websockify ???
how xpra identify printers and creates printer queue for that session !!

The actual code can be found here: browser/xpra/trunk/src/xpra/platform
(just look for all the "printing" files there and in each platform specific subfolder)

No.
Browsers do not allow Javascript code to query the hardware.
(just to clarify: printing from the HTML5 client should already work, and the print dialog should allow you to choose the printer - but this all happens within the brower's UI, client side)
This could be done using a browser extension (ie: activex, flash, native chrome extension, etc)
Then we would also need more code to skip the print dialog and go straight to the printer selected.
