Hi, I bought a few 2753 thermal printers. What I got is a smaller board without a test button and different layout that is labeled 2753B. This wouldn't be a problem as the pin out is the same, but I can't get it to print anything at all and can't find any documentation on the new board. Any help would be appreciated as I'm under time pressure to get this working :( via /r/DIY https://ift.tt/2O3QJEW
