1. On the laptop, select: Control Panel/ Printers /Add Printer
2. Choose Add Local Printer. (Yes Local, NOT Network.) Uncheck the box marked "Automatically detect my PnP printer. Click Next
3. Select Create a New Port and leave the default in the drop down selection as Local Port. Click Next
4. Windows displays a small dialogue box asking a port name. Key in
\\Host name\printer name
Host name - is the name of the desktop eg User-judf5564 or Home etc.
Printer Name - is MP530 or OffcPrnt, etc.
Click OK
5. Windows will show a list of printer vendors and models. The list looks just like the Windows Add Hardware Dialog. Select your printer manufacturer and printer model from the list. My particular model wasn't shown so I clicked on Windows Update. After an interminable wait the list of models was updated. I chose the closest match and will update the driver later.
6. When offered, indicate that you want a test print.
