Timeout problem using Words with "R" at the beginning of a line

With some String combinations the connection times out. Still unclear what it is causing it, but it is reproducable:

./dymoprint -s b "Rose Regenbogen" "" "03.05.2017"
Printing label..
Traceback (most recent call last):
  File "./dymoprint", line 576, in <module>
    main(args)
  File "./dymoprint", line 570, in main
    lm.printLabel(labelmatrix)
  File "./dymoprint", line 202, in printLabel
    self.rawPrintLabel(lines, margin=margin)
  File "./dymoprint", line 224, in rawPrintLabel
    response = self.sendCommand()
  File "./dymoprint", line 103, in sendCommand
    responseBin = self.dev.read(8)
IOError: [Errno 110] Connection timed out

The device needs at least a power-cycle to run again.

That is weird. It is working perfectly with or without R for me…

Ha! Got it (WTF included):

./dymoprint -s b " Rose Regenbogen" "" "03.05.2017"

It is the R at the beginning of the line. Adding a empty space in front works like a charm.

How i got it:

./dymoprint -s b " Ranunculus asiaticus" "Asiatischer Hahnenfuss (Mix)" "03.05.2017"

Same thing.

Yes, it is only R. r at the beginning of a line works fine.
