Special actions to do in UNIX to avoid blank page:
The host printer set up in unix, have to be changed at the _Z attribute.
Attribute _Z=! is the correct value
The path to the configuration is:
SMIT -> devices -> printer plotter -> print spooling -> programming tools -> change/show printer attribute database (virtual printers)
In this area, changed the "_Z" parameter as described below. The attribute "_Z" should have the value "!".
Example of how to do this with a simple command (see before, modify, see after):

/usr/sbin/lsvirprt -q lp69 -d 'hp@'lp69 -a _Z
/usr/sbin/chvirprt -q lp69 -d 'hp@'lp69 -a _Z=!
/usr/sbin/lsvirprt -q lp69 -d 'hp@'lp69 -a _Z
