chvirprt and tray 1

Hi,

I'm not able to print on tray 1. I checked the configuration and I get
these 3 options:

$lsvirprt -q print1 -d hp@xprint -a _O

Name Description Value
_O Type of INPUT PAPER HANDLING (backward 1
compatibility purpose only)

$ lsvirprt -q print1 -d hp@xprint -a _u

Name Description Value
_u Input PAPER SOURCE 6

$ lsvirprt -q print1 -d hp@xprint -a _Q

Name Description Value
_Q PAPER SIZE override for input paper source %IwQ

But it prints on tray2, my goal is to be able to print on tray 1 and
I
have to put the papers manually.

Have you any suggestions?

Thanks a lot.

Imad
