I had success getting the HP Color LaserJet 3550n (the 3550 family ) printer to install in Win7. That printer was the only thing that did not fire up with Win7. In the Devices and Printers window, I tried troubleshooting, but it was a problem with the DOT4USB drivers. Similarly to others, I was successful by using the following course of action:
1) Went to HP and downloaded the Vista 32-bit drivers for the 3550, unpacking them at C:\HP CLJ3550\ as suggested by the driver file.
2) In Devices & Printers, did <Right-Click> <HP 3550> <Properties> <Hardware tab>
3) I selected the first "Device Function" <DOT4USB> then did <Properties> <Change Settings> <Driver tab> <Uninstall>.
4) I then selected the second and third Function (which were <HP Color LaserJet 3550> and <IEEE 1284.4 compatible printer> and did the the <Properties> ... <Uninstall> for each.
5) I disconnected the USB to the printer, went back to Devices & Printers, and selected <Add a Printer>.
6) I selected <Add a local printer> <Use existing port DOT4_001> <Next> <Have Disk> <C:\HP CLJ3550> <OK> and installed the printer.
7) It would not work unless I "let" Windows make it the Default Printer
8) After it was finished, I did <Right-Click> on my preferred printer and selected <Set as default printer>, and everything worked.
Solved! Go to Solution.

Brilliant! Why the hell can't HP just say they are not supporting a printer but say that other drivers might work but with limited functionality (perhaps)? In the case of the 3550 I have had to connect it via home network. The original PC is XP and the new one is W7. Even when trying to connect to the printer attached to the XP machine via the network you need drivers .I used the clj3550hbwinvistaxp2003-64 which is the 64 bit Vista drivers and this worked much to my amazement. I'm thinking now I could have just connected it straight to the new machine with the drivers but it has been a long and evolving process. Incidentally, a network between W7 and XP is also a hassle but got there eventually.

Maybe because that wouldn't encourage you to give up your perfectly-good printer for a new one? I'm glad to have found this answer. I love our 3550n printer and it works on Snow Leopard without any fuss as well as XP too. I never expected to run into any incompatibility issues when upgrading to 7.

I want to thank you for the solution. You saved me the expense of having to purchase a new computer. I used the 64 bit 2003 version and it works just fine. The people at HP were not very cooperative at all. When I called, the lady who answered the phone asked if I was from the United States or Canada. When I stated the United States she had a big sigh
of disgust. When I explained my problem that I was having with the 3550 Laser jet and HP not having the Window 7 drivers, and that the printer was non functional, she stated that I should have researched whether or not my printer was compatible with a new operating system before purchasing it. I asked her if HP would have a compatible driver soon as I did not want to have to purchase a new printer. Then she stated that my printer was old (I bought it in 2005) and what did I expect,t as if the printer not working was my fault. I told them about your solution to this problem and if they could help me through the step but she did not cooperate .Even if I had to pay the $39 fee to the tech dept for their assistance it was worth it saving time. HP service in my opinion is very poor and will lean toward a competitors product if I am faced with a choice. Thank you again.

I had a similar problem with my HP3550N on a Windows 7 64 Bit Desktop. Since There was a Windows 2003 64Bit server on the network, I installed the HP3550N 64 bit drivers there and used it as the print server pointing to the ip address of the 3550N. HP has 64bit drivers for the 3550N for Windows 2003.
All the 64bit Windows 7 machines can now print on the 3550N via the Win 2003 server.

I have an HP Color Laserjet 3550 which ran just fine in XP Pro SP3 32 bit. But when I upgraded to Windows 7 Ultimate 64 bit, it wouldn't work. Just downloaded the XP Compatibility add on, but not familiar with it. Tried your suggestions above without success. Help!

Problem solved. I downloaded and installed the Windows XP 64 bit driver for the 3550, and Windows 7 installed it just fine. Just ran a test print flawlessly.

I, too, was dismayed that HP did not (purportedly) provide driver support for the HP3550n in Windows 7 (x64). After conducting some research and finding this discussion thread, I tried installing the Windows Vista x64 driver and, voila!, the printer works just fine on my new Windows 7 machine.
