Digital BW, The Print

I am in the same situation that you are (were) in.  I bought a 1280 
and was about to invest in Piezography until I started hearing about 
both how well the 2200 B&W prints are along with the clogging 
problems with Piezography ink.  What did you conclude?

I do not print very frequently (anywhere from 1-4 weeks between print 
jobs)...I didn't have a chance to scan all the messages, but is 
anyone saying that CIS systems are not appropriate for users like me 
since the setup stays idle?  Or is clogging something that we will 
experience independent of whether it is CIS or cartridge?

thanks in advance
