You may on rare occasions find that your document has not output in the colours you expected or with some strange characters. As a first step we recommend disabling 'PostScript Pass-through'. The steps to do this are:
1. Go to the Print Driver Preferences
![Default print settings… Default print settings…](https://www.ucl.ac.uk/isd/sites/isd/files/styles/medium_image/public/migrated-images/default-print-settings_0.jpg?itok=ccniL4Og)
2. Select the 'Advanced' tab and expand the Driver section by pressing the small '+' next to the word 'Driver'

3. Change the 'PostScript Pass-through option from 'Enabled' to 'Disabled' and then press 'Ok' to save the settings

4. Re-send your print job and collect
