Yes many of the new HP products have very small footprints. Keep in mind that a lot of HP features are designed as much to provide a digital on-ramp to electronic documentation as they are to push out huge volumes of paper. However, if your machines are doing 250K pages a year, HP products have no problem keeping up. If you have machines doing a million pages a year, I would say that HP does not play in that field. So much will come down to closely looking at what sort of page counts you have accumulated on your machines. Also clients often end up with features that are rarely if ever used, A3/11x17 printing for one, we have clients that purchased machines like this an only print 20-30 11X17 pages in 5 years.
But then the client has also spent 3x as much on capital expenditures. Will that product be more reliable? In most cases yes. What our experience shows is that many companies were dramatically oversold in the past and so hardware designed to do 5 million pages is put into an account that only does. We are typically the incumbent for printers and have excellent rapport with our clients and as HP has developed bigger and better MFP devices we are always looking for a bigger slice of the pie. The company I work for spends it's time in these exact situations.
