We have a combination of Secure Release and Direct Printing. Each should function with our external billing and charge the external account once the Pharos purses have been depleted. This is working correctly with the Secure Release as we have configured the script in the Billing plug-in for the Bank. However, this doesn't exist for Direct Printing. From what I've found, the Direct Printing uses the Print Server bank. So, I configured the Billing plugin for that bank as well, but it doesn't seem to be allowing the printing through direct print to charge the external account.
What am I missing?
