A. Background
Any file sent to the Jetdirect ftp service is printed.
Because certain ftp directories have write permissions
some security scanners report errors.
B. Recommended solution
If you wish to restrict printing or suppress the security
scanners warning, the ftp service can be disabled.
To disable ftp, telnet to the Jetdirect device and type:
ftp-config: 0
When this change is made printing via ftp will no longer
function. It will also not be possible to update firmware
via ftp. The firmware can be updated using the
HP Download Manager or Web Jetadmin.
