I've always had problems with the combination of User Codes and Mac printing. We have an office that is 90% Mac and they have decided to implement user codes. With Windows, piece of cake...embed them in the driver and you're done. With Mac, I've used CUPs and some of the OS' allowed me to enter it as a default setting in Job Log but most haven't. When unable to I set up a preset titled user code and tried to train the customer to select this preset when printing...however, when printing from Chrome browser they have to select "print using system dialog".
It doesn't seem like it should be this difficult. But, did I mention it was Mac?
Any help appreciated.
