Except for hard-core business. Oh, you can certainly use an inkjet for those color pie charts and presentations. You can use it to print digital photos of homes or clothes or cars or anything else. The text page printed on an inkjet just looks, well, home-made. And that's not always what you want in business.
Laser prints are still the standard.
Because they melt black toner dust onto the page, the same way a copy machine does, they have a distinctly different look from the ink-squirted page. The type of paper they can use is also different from inkjet's favorite foundation, which is also part of the appearance difference. Lasers can do their regular work on copy-machine paper, which, by looking less special, is somehow more businesslike, at least for regular business reports, memos and anything else short of a special presentation. That's not really asking much, at least where cost is concerned. Even the best only cost double that.
