node-print | printf in JavaScript | Runtime Evironment library

I am trying to install the this node-printer npm package. There is a pre built node build section under which there is:

I'm writing a Node.js application that use external devices, such as printers and smartcard readers.

I'm trying to write tests for the functions that use these devices, and my ultimate goal would be to setup CI for my project. However, I have no clue if it is possible to mock hardware devices for this purpose, or if it is possible at all.

If that helps, I use the graphene module for smartcard readers, and the node-printer module for the printer.

I have the proper CUPS drivers installed: I can print to my Star TSP143LAN using any application with print capability (like Chrome). I can print to this printer using the node-printer module, by specifying either the printer name or the printer’s network address, and setting the print mode to TEXT.

But I can’t seem to format what I print from NodeJS using the node-printer library. If I set the mode to RAW and send commands as specified in Star’s Command Line Emulator manual for this printer, node-printer will report a successful print but nothing happens. It doesn’t print.

I’m attempting to send these RAW commands because I want to do various formatting operations like make the font larger or bold, and so on.

I’ve tried the node-thermal-printer module but I’ve had no luck.

I’ve been scouring the internet for some help on this issue but I haven’t been able to find much. I’ve seen it mentioned that the TSP143 LAN doesn’t communicate in the same way as other star products and it’s best to use Star’s drivers as a go-between, but I’m not sure what that means. (I thought I might be doing that already when specifying the printer’s class name when attempting to print from node-printer...)

I didn’t have much trouble implementing the Star Swift SDK into an iOS app and doing formatting operations there. But I need to print from a NodeJS environment on Linux. I’m at a loss.

If there’s anybody to whom this sounds familiar and can point me in the right direction I’d be very grateful...

Thanks!

I'm currently working on trying to print a .lbl file using Nodejs. I've been digging around on npm and google but, I'm not quite sure what is the best route to go. I was thinking of modifying one the npm to incorporate the printers i need. However, if there is a general NPM out there that would be better.

Some background info for anyone interested: I would like to use the printer I have selected from the dropdown. Once select call the .lbl file and print the correct quantity from a box next to my printer drop down.

I would need to replace some values on the label with various things i have selected elsewhere on my screen before it prints.

I am using a Datamax-O'neil printer here but there may be different printers at other places.

My questions to you: Is there an node packages anyone might recommend? I have looked at node-printer, cordova-plugin-thermal-printer, and dymo along with more. The listed three seem be sort of in the right direction.

Do you know of any example I might be able to look at that might point me the right direction?

Sorry if this a duplicate question, I appreciate all the help and thank you in advance.
