Meanwhile, the printer with the RUMBA just keep doing what it is told with no fuss.  I'm out for the next week or two but after that I guess the SD4 will get the RUMBA as soon as I have some time to work on it more.

I had this same problem on my sd4.  It went away when I put the printer and the computer together on a conditioning/filtering power strip.  Putting just one or the other on it didn't fix it - both had to be plugged into the same, filtered, supply.

Can you link the one you used successfully?  Looking on amazon I see these for anywhere from $70 to $300.  I've never shopped for these before, don't really know what I am looking for.  Thanks.

A new USB cable is on the way.  Should I also try another baud rate?  Any other suggestions?  Thanks.

My other printer is an SD2 with RUMBA and it has no issues with printing from either computer or tablet.

Eventually I will pop out the RUMBA from my SD2 but I want to design a bracket for the SD4 to put it on the side first.  I don't even know where to start trouble shooting the printrboard.  I knew eventually it would disappoint me but I wanted to get a little more time out of it.  Any suggestions?
