Printing with PrintNode
The default behavior when printing from Microsoft Dynamics 365 Business Central is that the printout is saved as a PDF document and needs to be opened in a PDF viewer before it can be printed. But, from version 1.0.3, LS Express can be set up to print directly to a receipt printer by using a 3rd party service: PrintNode.
