This is a check-in system written in python to print nametags for people who come to xFair. At xFair, there will be 2 lines to check in - an express line where people need only to scan their ID, and a regular line where people type in their kerberos and it looks up their information from that to print their nametag.
This software does not work with Windows
This printing works on both Mac and Linux. To set up, plug in the printer and find the printer name. It's usually one of the following:
- Macs:
DYMO_LabelWriter_450orDYMO_LabelWriter_450_Turbo - Linux:
LabelWriter-450orLabelWriter-450-Turbo
These names have to be correct for the printing to work. Next, copy the .env.config file over to .env and edit the appropriate values. This file will be loaded with the environment variables on startup. Finally run python app.py to run the checkin software. Every time someone is checked in, it will save the current timestamp and the person's email to checked-in-emails.log.
To exit the checkin software, press Control-C twice rapidly (or just hold it).
For nametag-like labels, the correct size is probably LABEL_WIDTH=760 LABEL_HEIGHT=410
For square, badge-like labels, the correct size is probably LABEL_WIDTH=410 LABEL_HEIGHT=410, but this could be wrong.
app.py: Used to bootstrap the program and contains the Checkin, Print, Log loop.
app/checkin:
Used to check people in and create a User object with the appropriately filled in fields. This user object is handed off to the printer to print, and to the logger to log.
app/logger: Used to log the checked in users to either a file or webservice. Currently, just writes to a file.
app/model: Used to hold all the models needed for the checkin library. Basically just the User model.
app/printer: Used to deal with rendering nametags and printing them. If you want to change how the nametags look, you can do it here.
Every time a label prints, the USB disconnects and reconnects. The consequence of this is that when you print two labels rapidly one after another, there is about an 8 second delay as the USB disconnects, finds the printer again, and starts the next job. Still looking for a fix for this one!
