Newer printers print very fast, so they also need around 500..800 Watts of

In our data center, most newer printers have been slower than our previous
printers, but admittedly we were intentionally downsizing. I think our
data center laser printer history goes something like:

2 IBM 3820 40 PPM printers

1 IBM 3827 94 PPM printer

1 Xerox 4090 90 PPM printer

2 IBM InfoPrint 70 70 PPM printers

2 IBM InfoPrint 1872 40 PPM printers

The IBM 382x and Xerox 4090 all used three phase power. The 3827 was before
my time. It had been replaced by the Xerox just before I moved into
mainframe operations. We still had the 3820s, which were rarely used. My
first official shift in operations was the graveyard shift. I went through
almost four cases of paper a night printing invoices on the Xerox 4090, plus
another case or so printing mainframe reports. Boy times have changed.
Sadly, we outsourced invoice printing long ago. Our InfoPrint 1872's have
pretty much been retired. Most reports go out via e-mail these days, and
what does need to be printed prints on printers outside of our data center.
