"Yep. The included wifi interfaces is attached to the system in such a way that your CPU will be busy just pushing the webcam stream out to the network. There's not much left with regards to system resources to actually run a print job. Don't use a Zero W, it's not recommended and more trouble than worth it in most cases."
takze problem je, ze wifi na zeru vytezuje procak dost na to aby tam jeste mohla fungovat kamera v nejakem lepsim rozliseni. ano chapu, ze pokud nekomu staci rozliseni co mely prvni fotaky v mobilech, tak to uchodi, ale me osobne to je nahovno, chce to aspon hd...
paradoxne se to da vyresit pouzitim usb, ale ne kamery jak jsem prasl predtim, ale usb network adapteru.
"In short, it works wonderfully with a USB-Ethernet adapter. I'm using an Edimax EU-4208 plugged into a USB hub along with the serial connection to the Mk3. Prints fine and streams video perfectly."
