It works!! finally, something that works on Unity! A lifesaver... It actually works well with my printer over a network and works perfectly using silent printing and normal printing as well.

Cannot print silently

If you need to print, PrinterPluginPro does it great. I recommend Denis, who is very helpfull, to leave a bit more informations. Manuel

I use it to print to a USB receipt printer. (Epson M296A) It seems silent print only works with direct connected printers, and not with printers in the network. (just as info)
