Cannot speak for later HP Laserjets, used the 4L many years ago (4ppm). As far as print quality is concerned, I woulnd't have any qualms about Epson Printers. I use EPL 5900, the EPL 5900L is even cheaper, and more suited to personal desktop use.
If you want lower running costs, or heavy use, you need to look at other models. This one got PC Advisor's award
