MODIFYING THE REGISTRY
Warning: Improperly modifying the registry may result in you needing to reinstall the Operating System. Therefore, I recommend you create a System Restore point prior to proceeding, and backup all registry keys prior to modifying them.
Removing any registry values created by third party applications
1. Start Registry Editor. To do this, click Start, click Run, type regedit in the Open box, and then click OK.
2. Locate and expand the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Environments\Windows NT x86
View the list of subkeys (subfolders). There should only be the following subkeys:
a.Drivers
b.Print Processors
3.Backup the registry key prior to making modifications.
a. On the File menu, click Export.
b. In the File Name box, type the name that you want to use for this key, such as WindowsNTx86regkey, and then click Save.
4. Delete all the subkeys other than the subkeys that are listed in step 2. To do this, right-click each subkey that is not on the list, and then click Delete. Click Yes when you are prompted to confirm the deletion.
Removing the registry entry for printer drivers
1. Start Registry Editor if it is not open. To do this, click Start, type regedit in the Start Search field, and then press ENTER.
2. Locate and then expand the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Environments\Windows NT x86\Drivers
The registry entries for the printer drivers that are installed on the computer are stored in the Version-x subkey or subkeys, where x is a number (typically 2 or 3).
3. Export the Version-x subkey or subkeys. To do this, follow these steps:
a. On the File menu, click Export.
b. In the File Name box, type the name that you want to use for this key, such as PrinterDriverRegKey, and then click Save.
4. Expand the Version-x subkey or subkeys, and then delete the printer driver entries. To do this, right-click each printer driver subkey, and then click Delete. Click Yes when you are prompted to confirm the deletion.
Remove third party registry entries for default print monitors
1. Start Registry Editor if it is not open. To do this, click Start, type regedit in the Start Search field, and then press ENTER.
2. Locate and then expand the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Monitors
3. Export the Monitors sub-key or subkeys. To do this, follow these steps:
a. On the File menu, click Export.
b. In the File Name box, type the name that you want to use for this key, such as MonitorsRegKey, and then click Save.
4. Now delete any sub-keys related to the printer you are attempting to remove. To do this, right-click the subkey that you want to remove, and then click Delete. Click Yes when you are prompted to confirm the deletion.
5. Exit Registry Editor.
6. If you have a printer attached to the computer, disconnect the printer cable from the computer, and then restart the computer.
You will then want to restart your computer and reinstall any software that came with your printer. Attach it only when prompted to during setup to ensure that a generic driver is not installed.
I just wish I knew what caused the fuckup in the first place. Since my printer is the only A4 we have in the office, it was driving people and me nuts.
