Printboy

A simple service to print labels.

This is built for personal use case of easily printing return labels from a Raspberry Pi but there is no reason it couldn't be altered and improved for your use-cases.

It works by "generating" a label on a HTML canvas which is saved as a png and then printed via an lp command.

Setup

Print install

The first thing to do is ensure the printer works via CUPs.

A lot of this is from these articles:

• https://www.baitando.com/it/2017/12/12/install-dymo-labelwriter-on-headless-linux
• https://www.taklischris.info/other/use-your-dymo-printer-on-ubuntu

1. Install CUPs sudo apt-get install cups cups-client printer-driver-dymo or sudo dnf install cups-deve;
2. Get printer definition
   1. git clone https://github.com/matthiasbock/dymo-cups-drivers.git
   2. sudo mkdir -p /usr/share/cups/model
   3. sudo cp dymo-cups-drivers/ppd/lw450.ppd /usr/share/cups/model/
3. Add yourself as a cups admin sudo usermod -a -G lpadmin your-username
4. Go to CUPs admin page http://localhost:631
   1. Use your computer login credentials for the username and password for the site
5. Install the printer
   1. IMPORTANT: Use DYMO_LabelWriter_450_Turbo for the printer name, otherwise printboy will no work.
   2. Label sizes are use are:

2. Run sudo nano /etc/nginx/sites-available/default

   1. Change the location / { block to use:

      location / {
              # First attempt to serve request as file, then
              # as directory, then fall back to displaying a 404.
              # try_files $uri $uri/ =404;
              proxy_pass http://localhost:1314;
              proxy_http_version 1.1;
              proxy_set_header Upgrade $http_upgrade;
              proxy_set_header Connection 'upgrade';
              proxy_set_header Host $host;
              proxy_cache_bypass $http_upgrade;
              proxy_cache_valid 5m;
      }
      

3. Check for errors with sudo nginx -t
