//! escposify - A ESC/POS driver for Rust
//!
//! ## Examples
//!
//! ### sample.rs
//!
//! Write to a temporary file using [device::File].
//! ```rust
//! 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.
//! ```no_run
//! 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()
//! }
//! ```
