I have a Lexmark 3500-4500 Printer & Scanner that I no longer need.
The scanner works well. I tried it with two different laptops and different operating systems (Windows and MacOS). It is possible to find the software / drivers from the Internet.
I never used the printer, so I can't be sure if it works or not. I guess it will work, but you would need to buy new ink cartridges.
The device works with USB cable and with Wi-Fi connection. I always used it with a USB cable, so I can't confirm whether the Wi-Fi connection works.
The scanner lid is a bit broken on one side, but it does not affect its functionality.
I do not have any CD / DVD, so you would need to check if you find the installation software / drivers on the Internet.
I can't find the USB cable for connecting the device with the computer, so you would need to find / buy one.
The device is a bit heavy.
Dimensions are: 46 x 35 x 18 cm.
Contact me only if you are interested to collect the device, and mention your availability.
