escposify - A ESC/POS driver for Rust
Examples
sample.rs
Write to a temporary file using device::File.
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);
printer
.chain_font("C")?
.chain_align("lt")?
.chain_style("bu")?
.chain_size(0, 0)?
.chain_text("The quick brown fox jumps over the lazy dog")?
.chain_text("敏捷的棕色狐狸跳过懒狗")?
.chain_barcode("12345678", "EAN8", "", "", 0, 0)?
.chain_feed(1)?
.chain_cut(false)?
.flush()
}
Printing to /dev/usb/lp0
When writing to a file ensure that File::options().append(true)
is set otherwise writing is not possible.
use std::fs::File;
use std::io;
use escposify::printer::Printer;
fn main() -> io::Result<()> {
let device_file = File::options().append(true).open("/dev/usb/lp0").unwrap();
let file = escposify::device::File::from(device_file);
let mut printer = Printer::new(file, None, None);
printer
.chain_size(0,0)?
.chain_text("The quick brown fox jumps over the lazy dog")?
.chain_feed(1)?
.chain_cut(false)?
.flush()
}
