Installing printer drivers on Windows computers [continued] ...
Select LPT1 if the printer is connected directly to the computer. Select Create New Port if you are setting up a JetDirect Card (internal print server). JetDirect card setup is covered in the Network printing tutorial.
Select Have Disk.
You will need to browse to the folder where the files were previously unzipped.
In our case the folder was C:\HP LJ 4200-4200L\
Double click on the folder where the driver files are located. Select the .inf file and click open.
Click OK at the next box. Select your model.
Choose "Replace the existing driver".
Continue through the rest of the Add Printer Wizard by selecting the appropriate options that apply to you.
