Secure printing allows you to print to a copier, but have it wait in a user box until you input an ID, a code, and press Start.
From the application
File > Print > Printer Properties > Basic tab > Output Method: Secure Print
Secure Print ID: <your user name>
Password: <use up to 8 digits>
From the copier
Menu (top right) > User Box > System > Secure Print
Document ID: <your user name>
Password: <the password you used>
From this point forward, the steps are self-explanatory. Also, after the document has printed, it is removed from your System user box.
The application will remember your last print choice, so if you want to undo the above, change the Output Method back to Print.
