| | Old PPDs can remained cached on your computer, even though you have uninstalled and reinstalled the program or printer using the PPD, and can be wrongly used instead of the correct updated PPD. Warning: The procedures that follow entail editing the Registry. This can be a very dangerous thing to do, so you should always take a back-up copy of the registry before you edit it.  | |  | | To clear the cached PPD on Windows 95, Windows 98 or Windows ME... | | | | |
- Go to C:\Windows\System. Delete all the PPDs that you want to clear from the cache.
Note: Be careful not to delete the PPDs for your networked printers, unless you want to, or you will have to set them up again. - Go to Start>Run and type "regedit" (no quotes).
- Under HKEY_Local_Machine
>System >CurrentControlSet >Control >Print >Environments >Windows 4.0 >Drivers Delete only the folder that corresponds to the printer you want to refresh the PPD for.
  - Restart your computer.
You should now be able to add any PS printer. Simply set up the printer again. This will allow the PS printer to be used with the new PPD.
