Crate thermal_print 

Support for the CSN-A2 thermal printer via embedded_hal. This crate also supports bitmap printing via tinybmp.

Usage

Create a new Printer on a serial port on your platform and write text via the implemented core::fmt::Write trait. You can use the write! and writeln! macros to accomplish this.

See the Printer struct documentation for advanced capabilities, such as printing barcodes and bitmaps.
