for this print job:
The password must be between 4 and 12 alpha-numeric
characters. Numbers 1 to 9 and letters a to z are all valid.

password, click the [Always ask for password] checkbox

5. Select the required erase option for your print job:
> No overwrite: simply erases a print job without over
writing the job with data. This erase method poses a risk
of the print job being reconstructed.
> Zero out once: erases a print job after over writing it with
data once. This erase method is safer than the “No
overwrite” option however it still poses a risk of the print
job being reconstructed.
> Multiple Random Overwrites: erases a print job after over
writing it with data three times. This is the safest method
of erasing a print job however it takes longer to complete
the job.
