Hp Laserjet 2550ln Toolbox
Recently, I got an old(er) HP color laserjet 2550L printer and wanted to install it. Driver installation was easy and the printer was accessible immediately through my network print server.

But: the printer needed to be cleaned. This page explains how I solved it. Perhaps I need the information some time in the future – or perhaps it is useful for someone else. According to the manual, this requires the HP Toolbox and some special “clean page”. After about 45 minutes of searching, I had to admit that HP does not provide this toolbox as download. And I do not have the CD, I only got the printer.

Eventually, I found some download (even for the right printer model) at I installed the toolbox – and it is unable to access the network printer (which is connected to a printer server’s LPT port and that printer server is configured as local TCP printer port on my machine). I fetched a long LPT cable and connected it immediately using plug and play – and the toolbox found it. However, printing the “clean page” using the toolbox resulted in a fatal error in the printer (indicated by permanend light on warning LED, ready LED, and start LED).
According to the manual, one needs to reboot the printer. Fair enough, can happen from time to time.
After the reboot, the HP toolbox could no longer find the printer although test pages work. My excessive use of test pages seems to have a cleaning effect as well which is good. Rebooting the machine (in order to restart the java web service of that toolbox) did not help. I opened the printer properties of my locally connected printer driver, and fiddled around with the port settings. Eventually I realized that if I switch the port to LPT1 and back to the strange DOT4001 which was created by the windows plug’n’play stuff, the HP toolbox found it.

Retrying to print the clean page confirmed that the fatal error is reproducible. Fortunately, the cure with switching to LPT1 and back to DOT4001 is also reproducible (I mean: the HP toolbox finds the printer again). It has a different cleaning mechanism which appears to be better: at least it does something.
We’ll see if that is enough.
