The box and manual says it supports USB and USB hi-speed systems and cables. I
took that to mean it would do 480Mbps because that's what hi-speed USB is.

I really need to get a tool to show the connect speed in Windows in case this
is a Linux USB bug, which has happened before. My iPod used to fail to connect
at 2.0 speeds until some kernel revision came out.

That's good to know.

If this printer does not do 480Mbps, then it is a case of false advertising,
because it clearly claims to. I doubt I'd return it because of that, but it
would put a damper on things.

Most of the time, I won't care because PostScript and PCL are fairly
small for most jobs.

It is when sending large images that USB normal speed is painful.
