Unfortunately I had to disable the bidirectional communication when I installed the autoswitchbox.

What is the best way to purge the print buffer? The only way I have seen is to unplug the darn thing for a couple of minutes. I know that I could reduce the printer timeout time, but I am not sure if that will have unattractive and unforseen ramifications...

That print box from your link is very nice, but a bit pricey...

Do you know if the bi-directional communication is possible with a manual switchbox?

Thanks for the input!!
