A rugged machine

The HP 6L laser printer in my office has taken quite a bit of abuse, and yet it still continues to perform admirably. As a computer consultant, I have come to recommend only two brands of printers: Epson and HP. The others may be less expensive, but they do not give the same level of service and hassle-free service.
I am using the HP LaserJet in an Israeli environment, using 220V current, and with a Windows NT machine. At one point, some work was being carried out in my office, and the paper-feed mechanism of the printer was filled with dust from the plaster walls. Some secretaries carelessly continued to use the machine without even turning it upside-down in order to spill out some of the residue from the dust that landed in it.
To this day I don't think that they spilled out the dust and dirt - and I'm afraid to touch the machine. Nonetheless, it continues to present high-quality print jobs with no problems.
We didn't even have the correct NT driver (I don't know if there is one). We used the HPLJ5L NT driver instead, without any problems. It even printed the Hebrew text perfectly.
Highly recommended.
