Printing

Progress

Patch 1

First single threaded implementation in 389ad04e19.

Issues

The software will crash if no printer is found.

TODOs

No-printer mode

Allow to start the software without a printer connected.

Error checking

python-escpos issue #143
escpos-php issue #43
It seems that py-xml-escpos supports error handling.

Ideas

Custom receipt graphics

We could also store in a given folder such as static/events the asset files for each event, such as an image to print in the receipt.

The software could check for the presence of a file (in example <Event.uid>.png) in that folder and would eventually print it.

We could also add some flags in the database concerning the event. For example there could be a flag to hide the Macao logo in order to only print the event image.

There is also another library we could alternatively use: py-xml-escpos.
