One of my requirements is to not directly expose any server to the internet. Thus, we cannot use OctoFarm directly to view the printers from a remote location. The solution I came up with was to take an automated screenshot of the panel view using headless Chrome. This works fairly reliably. I had to fiddle with the command-line settings to ensure the html page was rendered completely, but once I got the settings worked out, the screenshots were clear and reliable. | One of my requirements is to not directly expose any server to the internet.

If we implement OctoFarm, I would put a cron job on the RPi running OctoFarm to take a screenshot every few minutes and upload it to Azure. We could then serve up the latest screenshot and protect it using our AD accounts (I need to double-check with the Tech Team, but I believe this is possible with our current Azure setup). Members could then use their normal network credentials to access the printer status. Hosting and traffic costs for serving a single PNG to the membership would be | If we implement OctoFarm, I would put a cron job on the RPi running OctoFarm to take a screenshot every few minutes and upload it to Azure.

There may also be other ways to host the image (wiki, existing web server in the space, etc). | ||
