Struct thermal_printer::ThermalPrinter

pub struct ThermalPrinter<T>where
    T: Write<u8>,{ /* private fields */ }

ThermalPrinter wraps a serial port to provide a high-level abstraction over the printers serial protocol.

Implementations

impl<T> ThermalPrinter<T>where
    T: Write<u8>,

pub fn new(port: T) -> ThermalPrinter<T>

Creates a new thermal priner on the given port, with the default settings Once you have successfully connected to the printer you can update these settings using configure

pub fn configure(
    &mut self,
    dots: u8,
    time: u8,
    interval: u8
) -> Result<(), T::Error>

pub fn run_test(&mut self) -> Result<(), T::Error>

Run the printers internal self test

pub fn justify(&mut self, just: Justification) -> Result<(), T::Error>

Set the character justification

pub fn feed(&mut self) -> Result<(), T::Error>

Feed a single line

pub fn feed_n(&mut self, n: u8) -> Result<(), T::Error>

Feed n lines

pub fn set_underline(&mut self, n: u8) -> Result<(), T::Error>

Set the underline mode

pub fn set_bold(&mut self, flag: bool) -> Result<(), T::Error>

Enable bold printing

pub fn free(self) -> T

Consume the printer, freeing the underlying serial port
