IPP over SSL

[Johannes Grumboeck]

Hi,

I've got a HP Laserjet 1300 connected to a HP Jetdirect 500x.
On my CUPS-Server I added the printer with the URI: http://<ip>:9100/ipp/port1
and it works perfectly.
Now I like to encrypt the print data. As I believe this should be
possible with IPP over SSL, but when I enter https://<ip>:9100/ipp/port1
it won't work. I also tested https://<ip>/ipp/port1.

Does anybody know how the correct URI should look like?

TIA and kind regards,

Johannes Grumboeck
