Digital BW, The Print

I'm using QTR with Jon Cone's piezography, a combination working well
for me.

But I'm going to be on a long trip in March/April and don't want my
inks to dry out.  Jon suggested there was a program to automatic print
a test sheet everyday to keep the heads unclogged, a Windows XP based
routine which is the basis of my computer.

Does anyone know about this and/or use it?  It would be very useful as
I could load in a lot of plain paper sheets and just let it run.

Other suggestions for a long shutdown would be welcomed.
