Hello everyone, thanks in advance for the help here!
So like the title says, I installed a Kyocera Ecosys M6630cidn a few weeks ago and a couple of days later the optional tray came in as the user needs to print LT and LG using mixed size printing. Once I installed the optional tray, I tried printing mixed size from the MAC and no go, I sent same file from Microsoft works fine no issues. Latest driver on Kyocera site is from May and specifically claims it's for this type of printing however doesn't wok on this MAC. I'm assuming the High Sierra OS 10.13.6 is a bit older and I'll have to update to Mohave first and Catalina which is latest OS unless I can skip Mohave. Any suggestions are welcome as I'll be heading there tomorrow and will have more information to use from you guys! Thanks a bunch!
