Have you ever done it to print various size labels? I've researched many options and with mitsubishi GOT's I was not able to do it. They only support basic paper sizes for reports printing as far as I managed to do it...  I would really be interested to learn how you've done it since that can save a lot of hassle of transferring hex code to PLC and then printing using zpl code transfer from PLC as mentioned earlier (works very well though once set up properly).

If you struggle doing this and do have ethernet port on the printer, I would suggest switching to Ethernet. It's quite easy to set up using existing functional blocks for socket communication. Everything you need for that is available in Mitsubishi manuals under "ethernet socket communication". I've just recently done one of these applications using same PLC and Zebra printer and it works great.  Depending of the length of the string, you can end up using massive amount of PLC memory, but that's same for RS232 communication, I would presume... Good luck with your project.
