First, "Officejet" and "Laserjet" are brand names of a product. There's only inkjet and just simply laser (because there's no "jet")
Anyway, which is better really depends on your needs. If you rarely print pages out, laser printers are better because the toner doesn't "expire". Ink cartridges on inkjets can dry out over time, sometimes within months. So the next time you want to print something, you'll find out the ink cartridge no longer works. Laser toner cartridges are more expensive up front, sure, but it's possibly the same amount of money you would've spent replacing ink cartridges that dried out.
As far as quality is concerned, I think at this point it doesn't matter. However I have a gut feeling inkjet has potentially better quality, or at least options that give it better quality. If you're just looking to print things occasionally and not quality color prints, just go with a B&W laser printer.
