we recently bought kyocera 2020D printer. There are USB and LAN versions. 
We got cheaper USB as it is connected 1 meter from server anyway.

But seems there are some problems with USB
ulpt seems to work fine, device is connected at 480Mbps

but 2 page 5 megabyte postscript file is transmitted 10-15 seconds.

On Kyocera 3900DN which have EXACTLY same internal processor, same amount 
of RAM, but LAN interface and even similar printing mechanism and nearly 
same look - same file is accepted below one second to printer and soon it 
is printing it.

Larger postscript files are transmitted longer.

I am not sure but seems it is not printer problem. Any ideas what to 
check/change in ulpt?
