Cannot import node-printer in electron 7 app #274

Open plumbn opened 4 years ago

plumbn commented 4 years ago

I'm attempting to use node-printer in an electron 7.1.3 app. As per the docs, I've tried installing the library using npm install printer --runtime=electron --target=7.1.3 --target_arch=x64. It appears to install successfully but when I try to import it in main.js, I get the following error:

App threw an error during load

Since I'm getting an ELF header error, I wonder if I'm just importing it incorrectly. I'm using const printer = require('printer');. I also tried building after install as described in the docs and I tried using electron-rebuild. Both failed to build. Obviously that's not reassuring, but before diving down the rabbit hole of what's going on there, I thought I'd rule out the simple issue first. Any idea what might be going on?

@grahamnordstrom @thiagoelg/node-printer works without any issues for me, can you please direct me why this is happening on @tojocky/node-printer ?
