# Using [`scanimage`](https://man.archlinux.org/man/scanimage.1.en)
First, get the name of the scanner with
scanimage --list-devices
In my case, this produced
device `brother4:net1;dev0' is a Brother Brother_DCP-L3550CDW DCP-L3550CDW
To get the different options and capabilities of that device, run
scanimage --help -d 'brother4:net1;dev0'
In the output, following the line
Options specific to device `brother4:net1;dev0':
there were the supported resolutions, in DPI:
--resolution 100|150|200|300|400|600|1200|2400|4800|9600dpi [200]
I proceeded to do a test scan, to see if the resolution is actually supported:
scanimage -d 'brother4:net1;dev0' --resolution 2400 -o 'test_file.jpg'

[This helpful blog post](https://jvns.ca/blog/2020/07/11/scanimage--scan-from-the-command-line/) by Julia Evans pointed me to `scanimage --help -d`.
