Hi there and welcome
The drivers are built into windows. How are you connecting to the printer, via a USB cable?
Please click start, devices and printers.
Then click on Add Printer
Click on local printer and wait for it to appear
When it does, click on it and it will install it with the correct driver
Let me know please how you go
This actual computer has windows 7 on it correct?
install the windows XP driver from here
It should still work with this one
Let me know how you go please
