Digital BW, The Print

Hi All
I\ufffdm teaching art and photo at a high school. We are going to switch to a 
digital darkroom - Photoshop and Inkjet printing (B&W).

When it comes to printing I want a foolproof system. It all has to be 
easy to work with, cheap, good quality and no problems.
The conclusions, after following this list for a while, is:

1. For easy printout - use Piezography.
2. For economy - use CFS and Mis ink.
3. Printer - 1160

I\ufffdm thinking of using Mis FS-N inks.
Do I have to change the curves with Mis FS Neutral inks or do they just 
work perfectly with Piezography?

It seems that there are some problems with clogging. It is impossible for 
me to stand with students and looking at printer that\ufffds not working. How 
can I avoid clogging? Are there CFS system that don\ufffdt clogg?

My students will print a lot sometimes and sometimes the printer will 
stand for a week or two. Does this system stand for the pressure?

On hollidays and during the summer (2 months) no one will print. Won\ufffdt 
the system dry? How do I avoid it?

Thanks in advance
