Hi, I recommend first that you install Synaptic Package Manger, or even from the terminal, to install:
sudo apt install printer-driver-all
but noticed that Zorin have recently included this, so it might be present already.
I was going to suggest official canon website but it appears they no longer provide support for that model, only for Windows!
The best way to get the Printer to install is to start at the command line in a terminal (Just enter the word terminal in menu search bar, then press enter):
sudo system-config-printer
Next, click on Add - if networked, use AppSocket/HPJetDirect method and enter the IP Address of the printer in the top field. Then click on continue to select driver, then choose the iP2000 series driver:
If it is a networked printer, you may also need to stop 'Printers' from autodetecting the printer again by following my guide in the Unofficial Manual for Zorin 17 Core here:
