I recently bought and installed a new wireless router. Now I can't print to my network HP Laserjet 4200 printer from my MacBook Pro. I have an iMac on the same LAN and had no trouble, so I'm thinking that there is something corrupt on my MBP. How do I eliminate all references to old printer installs, relevant drivers, etc., so I can start fresh?
MacBook Pro, Mac OS X (10.6.7)
The printer drivers are installed in HD > Library > Printers. In your case there would be a HP folder which you could trash and then install the HP driver for 10.6.

Thanks for your reply. I did this, and now when I try to install the printer, I I cannot connect to it. I'm in Add Printer, and it is trying to determine installable options, but it it's been trying to connect for about 10 minues. Any ideas? Thanks!
With the Add Printer pane stalling on the determination of the installable options it would suggest that the Mac has an issue with communicating with the network LJ. Open System Preferences > Security and select the Firewall tab. If the firewall is on, turn it off temporarily to see if that helps. If it is already off, do you have any other anti-spy software installed? This could be blocking the connection. If you don't have any such software then you could try a reset of the printing system on the MBP. Here's the steps;
1. Open System Preferences > Print & Fax
2. Move your mouse over the Printers list
3. Hold down the Control button and click the mouse
4. Click the "Reset printing system ..." popup
5. Restart your Mac
This will remove your print queues but not your printer drivers. So you will only need to add your printer queues again.
With regards to adding the queue, what protocol are you selecting? Are you using the Default Add Printer view to locate the printer on the network (using Bonjour)? If yes, then I suggest you try adding the printer using IP > HP Jetdirect. This will require you to enter the IP address of the printer and then possibly manually selecting the LJ4200 driver in the Print Using menu.
Okay, I'm stupid. Turns out I had enabled network restrictions on the new router, so I couldn't connect to any network resource (except the Internet). Once I fixed this, the printer worked just fine. Thank you very much for your help!
how do I remove printer drivers?
