[Sussex] Secure printing

[Brendan BT Account]

We are quoting for an NHS job where they want secure transmission of
patient data. HTTPS will securely handle information between browsers
and the servers and we can encrypt/password protect any downloadable
reports. However, printing would seem to be more tricky as by default
Postscript and raw text files (to label printers) are unencrypted.
Secure Jet  (http://www.artimbilisim.com/urun09/SecureJET.pdf) would
seem to be handle laser printers. Has anyone experience in encrypting
printer output or any suggestions?  Thanks, Brendan
