As a related aside, a friend, who is an accountant, buys Brother laser printers and uses them until the cartridge is done then buys another. Claims it is cheaper than buying toner.
I won't go into the details of my past suffice to say that I have lots of experience supporting high volume printing before and after NMCI.
Everyone wanted color laser printers when NMCI came to the facility. And so they got them. What they failed to realize is that color laser printers used a very expensive wax cartridge system. While the printers were 'free' the ink ended up costing a fortune. Most of the stuff would have been just fine printed on cheaper ink jets. Then there were the Power Point Rangers who felt they needed to make a "complete package" of their slides for every person who might ever see them but always managed to send an unchecked draft version without checking the printer situation first. The draft version usually ate the ink leaving them scrambling to find more for the 'final' corrected version. You can always tell a senior manager, you just can't tell them much.
HP, at the time made the best highspeed lasers for my application. And for those in the high volume business, toner is not the only consideration, coronas can set you back a couple bills on your maintenance budget as well. We tried to use aftermarket toner in recycled cartridges but found it was more trouble than it was worth. Maybe for home use it would be ok. You never knew what you were going to get and after a while the maintenance crew refused to service a printer which had had recycle cartridges. It was a matter of consistency and low bid in our case.
In a production environment you do every thing you can to not have printers go down. Drivers become an issue to support specific applications so you just don't slap another printer on line unless it is identical. It is not all cupcakes and ice cream. When the paper stops the work stops. This is just a fact of life in a manufacturing operation. Someone always wants a "hard copy". You carry a beeper for a reason, 24/7 and come to dread the printer down call.
