Generating a prn file without printer initialization

Hi.

Do you have an example which creates a prn file instead of printing it directly to the printer?

I have a printer installed on TP-Link TL-WR1043N/ND v1 router running on openwrt. Since the file system of the router is too low and ram is also low, it is not ideal for nodejs applications. I can successfully print simple text to the printer inside the router however I cannot print complex styles to it since I need a library for it.

To solve the problem, the router will request the server running either local or public to generate my complex styles and send the generated prn file to router and the router print it to the printer. (Note: network printers is not my ideal solution since routers are not running on the same network as the others)

Currenly, the design of your code doesn't allow me to do so since it is tightly coupled to the Printer Instance. Could you separate the formatting and the Printer instance?

I hope you will implement this since this is an amazing feature where you will generate the prn file and print it anytime.

The issue identifies the Printer instance and formatting as the affected areas, but provides no file or test paths. Begin by locating those components and define the requested generated-PRN flow separately from direct printing; done means a PRN file can be generated without printer initialization and the behavior is demonstrated or tested.
