I installed the 3.90 driver for the an iMac with El Capitan. There is no features on the driver to allow it to configure the account setting for the user of the computer to print to the Xerox WC7545. When you print it give me an Error Notice: "the job was deleted due to invalid accounting IDs."
Our WC 7545 w/built in network, has accounting features set for printing. Able to print from Windows 7 and 10, Mac OSX 10.9 all with accounting configured on each computer but not El Capitan
