If you use a color managed printing workflow from within LR 2015.6 please be aware that there is a serious bug that will produce off colors. Others have reported the same issue and we can only hope that Adobe doesn't ignore this. I am currently working around this problem by printing from the ColorBurst Overdrive RIP, but other printing apps or utilities will also work. The problem seems to be that LR is not properly applying the printer profile before sending the file to the printer. This was not a problem in the previous LR version, only 2015.6 (CC) or 6.6.
