Send Percent complete to the Printer display
It would be nice have percent complete available on the printers display along with ETE ETA and Layer.
Latest dev repetier-firmware supports that protocol. It will show percentage as a bar if you have graphic display and also the file you are currently printing. Should work with latest server release.
Unfortunately all my printers are running marlin right now.
Maybe they will also support this soon. I at least told them about it and added it in case they add the capability.
