iPrint Profile - Hold Print help?

We are using iPrint (2.1.3). We are using RICOH copiers as printers/scanners and having issues with creating a Printer Profile to set Hold print as a default. This is proving problematic. When the profile is created, we set a User Name (tried both 'Test' and '1234' on different occasions). When the printer is installed, however, the User ID setting disappears. Gone. If the user sets a string in UserID field, subsequent print jobs will be held as desired, but if they have to visit this and set it manually anyway, what is the point of using a profile?

Please advise.
