probably also need to install _some_ of the libraries at https://github.com/adafruit/Python-Thermal-Printer but not all
`sudo apt-get install git cups build-essential libcups2-dev libcupsimage2-dev python3-serial python3-pil python-unidecode` maybe don't need alllll of it
Do need to do this to install the printer:
```sudo lpadmin -p ZJ-58 -E -v serial:/dev/usb/lp0?baud=19200 -m zjiang/ZJ-58.ppd
sudo lpoptions -d ZJ-58```
certainly CUPS will cause you issues and you will need to reference https://www.cups.org/doc/man-cupsd.conf.html
Now need to install an ARMv6 compatible NPM. This should work:
```
curl -o node.tar.gz https://unofficial-builds.nodejs.org/download/release/v13.8.0/node-v13.8.0-linux-armv6l.tar.gz

If that doesn't work you can [read more about installing node on arm v6 architecture](https://www.thepolyglotdeveloper.com/2018/03/install-nodejs-raspberry-pi-zero-w-nodesource/). Also [the builds are here](https://unofficial-builds.nodejs.org/).
might need to run `curl https://get.pimoroni.com/buttonshim | bash` to get the buttons to work

#### setup SSB
I can't remember how I got ssb-server to work, `sudo npm install -g ssb-server` throws `illegal instruction`. Something to do with a woknky version of Node. So my **extremely** hacky workaround is to unzip `ssb-server.zip` from the install directory into `/usr/local/lib/node_modules/`. This is v bad and needs to be fixed asap. [SSB-server](https://github.com/ssbc/ssb-server) is made available via the MIT licese.

##### My **extremely** hacky workaround:
1. `sudo npm install -g ssb-server` to add all the npm-side ssb stuff
2. unzip `ssb-server.zip` from the install directory into `/usr/local/lib/node_modules/` to actually have a working SSB server.

As long as the EBB repo is at `/home/pi/ebb` the following service files should be configured fine. Otherwise you gotta edit ssb.service and ebb-carousel.service and update the `WorkingDirectory` field.
