Unfortunately, the price we have pitched the plugin at does not allow us to help with any general printing issues. The plugin is a connector between PrintNode and your WordPress site, and we are only specifically able to support that aspect. (To use an analogy, if you buy new tyres for your car, then you’ll understand that the tyre supplier’s after-sales support will not include investigating engine issues). To use this plugin, you need to ensure that your printer, any device driving the printer, network and connection to PrintNode are all working, as pre-requisites. You can and should ask PrintNode for support with any issues with your PrintNode account and the associated service.
