Epson 9900 - Speed of USB vs Ethernet

[darlingm]

The Epson 9900 has USB 2.0 High Speed and 10/100 Ethernet.  I've been using the Ethernet connection.

Has anyone benchmarked if there's a real world speed increase by using USB?

USB 2.0 High Speed's theoretical max throughput is 480mb/s vs 100 Ethernet's 100mb/s.

However, the printer of course starts printing once it receives something, before the file transmission is completed.  So, I'm not sure if there would be a noticeable difference.

I often print large files like 30x40 @ 720dpi, 20x30 @ 1440dpi, etc.

I'd just try it, but I'd need a 16' USB cable which I don't have... Not that expensive mail order of course, but don't want to bother if it won't really matter.

There's no difference.  The printer can't print fast enough for it to matter.

Once it gets started printing, there definitely won't be a difference.  Could there be a difference in the delay before it starts printing, though?

This is an interesting question. I do suspect there will be some difference, but given the gyrations my machine goes through before even beginning to move the head for the print job, in the end I doubt you would find a notably different result.

No difference to start speed.
