That's a hoax -- I never had a print failure through USB.
Of course if you are sending from a laptop with power management and it decides to go to sleep, or is you start to plug things in the USB and the bus resets, then you are in trouble...
But in a controlled environment it is very stable.
In the old days, it was the only way to print on UMOs, there was no SD-Cards (Ulticontroller was an option)
