Connect to Printer error message

The base computer of my network that is directly connected to the internet and my router is a Windows Vista (32 bit) Operating system. My computer is connected through the network to access the internet and the printer connected to the base computer.
My computer was also running Vista and the networking worked fine.
I have received this error when trying to add a printer to my laptop:

Add Printer
Connect to Printer
Window cannot connect to the printer. No printers
were found.
I have added the printer to my brother’s laptop and nothing wrong with it. We add printers by navigating to the print server in explorer and double-clicking the desired printer.
Please advise me on what to try next.
