You need to follow these instructions on your PC, before logging into the VDI.

1. Click the Windows button in the taskbar.
2. Without clicking anywhere, type, Printers and Scanners.
3. Choose that option when it is displayed in the menu.
4. Click on the name of the printer you wish to change.
5. Click on 'Printing Preferences'.
6. The window displayed will vary depending on the printer model, but all look basically the same.  Search for the 'Job Type' section.  If this has a drop down menu, choose Locked Print from the menu.  Then click Modify.  Otherwise, just click the 'Modify' button.
7. If the drop down menu wasn't available in the last step, choose 'Locked print' here.
8. Click in the User ID box and type your name.  (You are limited to 8 characters).
9. Click in the password box and type a 6-8 digit number.  This is the number you will use when releasing print jobs on the copier.
10. Click OK.
11. Click OK again.
