As for uninstalling, reinstall the bootable backup/clone or Time Machine backup you made for each machine before installing the upgrade. What? Don't have any? Then, get a bootable, external HD (preferably FireWire, since it's 40-50% faster than USB 2 and designed for data transfers) for each machine, make a bootable backup/clone before updating/upgrading, and ensure that it's bootable and works like the original. That allows you to revert to the previous good state without having to reinstall anything. See these for details:
If you only have a Time Machine backup, insure that you can reliably restore it to another disk/volume/partition before updating/upgrading.
This is turning into a mini-nightmare for our small business. Since 10.6 won't recognize either of our HP printers, I see no alternative but to visit Best Buy tomorrow morning and purchase a new printer, hopefully one that 10.6 will recognize. Believe me, if I had know 10.6 wasn't ready to for use with older printers I sure as **** would have passed this update up, at least for now. What a headache!
I just read where a printer may not be recognized unless it's directly connected to one of out Macs. So I disconnected our HP LaserJet 4050n from our Airport Extreme router and connected it (via ethernet) directly to the computer. Nothing doing; when I try to "Add Printer", nothing happens. Obviously the computer does not recognize the 4050n at all. I think we're at a dead end here. We'll have to dump our older HP printers and update to a couple of newer units immediately. Not the end of the world, of course, but a real let down for us. I think my confidence in future Apple updates has taken a big hit. To me, 10.6 is not ready for prime time.
No Go on the Officejet 4315 either . Seems to be an HP thing. My Mac recognizes the printer, just says no driver. Hoping it will be cleared up in the next few hours. So much for jumping in head first. Next time I will wait to see how it works out for a others before I disable my whole system with the next new thing.
Did you try my suggestion above? My Hp printer decided (after the OS X 10.6 update) to only print the last page of multi-page documents. Deleting it, restarting, and then adding the printer back fixed my issue.
P.S. Waiting a bit is not a bad idea. A few of us enjoy dodging arrows (or pulling them out of our backs), but looking at these forums for a couple of days before making a major update is not a bad idea

Ed: The HP 4050n can be setup using an IP address. Force the printer to print a config page. Then see the outline here:
Basically: System Pref: Print & Fax: Add Printer: IP
Then enter your IP address and select JetDirect. Then Pick the 4050 PPD file.
The HP Deskjet F4100 series drivers (which work with the Deskjet F4180) are not included on the Snow Leopard DVD. Expect them to be available at some point in the future through and Apple Software Update. In the mean time if you have already upgraded all of your machines to 10.6 you may want to try installing the 10.5 software form HP.com. Its officially unsupported, some features will be missing or broken, but it might (and remember only might) work.
Just trying to help.
Drivers for the HP Laserjet 4050N are included on the Snow Leopard DVD. If the Mac is not recognizing the printer, first try resetting the print system and adding the queue back. If that still doesn't work try re-installing the HP driver package which can be downloaded here.

If the HP Deskjet F4100 series is not included on the Snow Leopard DVD, then why is it listed as supported on the HP website?
Here is the exact text from the HP site:
HP Photosmart, Officejet, and Deskjet All-in-One models supported in Mac OS X 10.6 Snow Leopard (Print, Scan, Fax, and HP Utility Functionality)
* HP Deskjet F300 series
* HP Deskjet F735
* HP Deskjet F2100 series
* HP Deskjet F2200 series
* HP Deskjet F2400 series
* HP Deskjet F2500 series
* *HP Deskjet F4100 series*
* HP Deskjet F4200 series
* HP Deskjet F4400 series
* HP Deskjet F4500 series
The Officejet 7300 series drivers are included with the Snow Leopard DVD. Try deleting and re-adding the print queue for the device. If everything is working right both a print and scan tab should show up for the device. If that is not the cast try re-installing the software. You can download the same software that came on the DVD here.
