Getting an HP scanner / multi function device to work in Peppermint

I have had a long standing problem scanning documents or photos with Linux (not just Peppermint).

You see, I have a Canon CanoScan LiDe 90, a model that is not supported by Linux. I spent a lot of time reading through forums and even trying a demo version of VueScan. It lists my scanner among the compatible ones, but unfortunately I could not get it to work. Well done for them to have a demo version, because if I had purchased the software and it had not worked - I would have asked for my money back.

I don't scan often, and I am able to use CamScanner on my phone if I have to, but sometimes it is a lot better to scan from a "real" scanner.

If it is a scanner only:

If you have an HP, this should work for you:

Click Menu >> Accessories >> Terminal
Type in: sudo apt-get install hplip-gui
press <ENTER>
Type in your sudo password and press <ENTER>
Press Y if prompted

Once it is installed, click on:
Menu >> Graphics >> Simple Scan

If it is a printer and a scanner:

You will need to install the printer first
Click Menu >> System Tools >> Printers
Click on Add
Select your printer from the list
Follow the prompts to install
