No recompilation required when upgrading Node.js versions, thanks to N-API! 🎉

Native bind printers on POSIX and Windows OS from Node.js, Electron, and node-webkit.

!npm version !Prebuild Binaries and Publish

> Supports Node.js versions from 8.0.0 onwards, including the latest versions, thanks to the transition to N-API.

I was involved in a project where I needed to print from Node.js. This is the reason why I created this project and I want to share my code with others.

* No dependencies on NAN or V8;
* Native method wrappers for Windows and POSIX (which uses CUPS 1.4/MAC OS X 10.6) APIs;
* Compatible with Node.js versions that support N-API, ensuring long-term stability and compatibility;
* Compatible with Electron versions that support N-API, reducing the need for frequent recompilation;
* getPrinters() to enumerate all installed printers with current jobs and statuses;
* getPrinter(printerName) to get a specific/default printer info with current jobs and statuses;
* getPrinterDriverOptions(printerName) (POSIX only) to get a specific/default printer driver options such as supported paper size and other info;
* getSelectedPaperSize(printerName) (POSIX only) to get a specific/default printer default paper size from its driver options;
* getDefaultPrinterName() returns the default printer name;
* printDirect(options) to send a job to a specific/default printer, now supports CUPS options passed in the form of a JS object (see cancelJob.js example). To print a PDF from Windows, it is possible by using node-pdfium module to convert a PDF format into EMF and then send it to the printer as EMF;
* printFile(options) (POSIX only) to print a file;
* getSupportedPrintFormats() to get all possible print formats for the printDirect method, which depends on the OS. RAW and TEXT are supported on all OSes;
* getJob(printerName, jobId) to get specific job info including job status;
* setJob(printerName, jobId, command) to send a command to a job (e.g., 'CANCEL' to cancel the job);
* getSupportedJobCommands() to get supported job commands for setJob(), depending on the OS. The 'CANCEL' command is supported on all OSes.

This project was originally written by Ion Lupascu using NAN and V8. It has been rewritten by @susheer to use N-API exclusively, removing dependencies on NAN and V8 to ensure better stability and compatibility with future Node.js and Electron versions.

$3

This project supports Node.js versions from 8.0.0 onwards. N-API ensures that native addons do not require recompilation when upgrading Node.js versions. For more details, refer to the Node.js N-API documentation¹(https://nodejs.org/api/n-api.html).

Feel free to download, test, and propose new features.
