escposify-rs

A ESC/POS driver for Rust

Documentation

Most ESC/POS Printers will appear as a file. To print to the device, open a file to the location and pass this to the File::from function.

To enable this in Windows, install the printer and its driver. Share the printer and specifiy a name for it (Receipt Printer in this case). The printer will then be accessable via \\%COMPUTERNAME%\Receipt Printer. To test this in the command line:

echo "Hello World" > testfile
copy testfile "\\%COMPUTERNAME%\Receipt Printer"
del testfile

Examples

Rust

See: simple.rs

extern crate escposify;
extern crate tempfile;

use std::io;

use escposify::device::File;
use escposify::printer::Printer;

use tempfile::NamedTempFileOptions;

fn main() -> io::Result<()> {
    let tempf = NamedTempFileOptions::new().create().unwrap();

    let file = File::from(tempf);
    let mut printer = Printer::new(file, None, None);
