This guide shows you how to switch on the Invoice Auto Print extension so posted invoices print automatically. For what the extension does and why you'd use it, see Invoice Auto Print extension: what it does.
Auto Print sends invoices to a NexerIQ printer agent, so make sure the printer you want to use is already set up and available. You'll select it during configuration, so it helps to know which printer should receive your invoices.
These settings are available in the configuration drawer when you enable the extension and any time afterwards via Configure:
Once enabled with Always print on and a printer chosen, you don't need to do anything — each time an invoice is posted, a PDF is generated and sent to that printer automatically. If you turn Always print off, the invoice screen prompts staff to print after issuing, so they stay in control of which invoices come out on paper.
Tip: if printing doesn't happen, check that a Printer is selected in the settings and that the printer agent is online. Without a printer chosen, Auto Print has nowhere to send the job and will quietly skip it.
