HP terminology: cxi vs. cse?

[slipgun]

Any idea how these two 'types' (?) of some of the 900-series HP inkjets differ?

While the printers are the exact same thing physically, the model suffixes distinguish differences in the software bundles included with them. "Cse" models are generally the ones you'll find at stores like Best Buy and include home/SOHO oriented software. "Cxi" models come with business-oriented software packages.
