MUNBYN ITPP047 Printer Library

A C library for controlling MUNBYN ITPP047 thermal printers, providing comprehensive support for text formatting, barcode printing, and character set management.

Features

• Text Formatting: Font sizes, styles, alignment, rotation
• Barcode Support: Multiple barcode types (Code128, EAN, QR codes, etc.)
• Character Sets: Support for multiple codepages and character encodings
• Cross-Platform: Works on Linux, macOS, and Windows
• Simple API: Easy-to-use functions for common printing tasks
• ITPP047 Optimized: Specifically designed for MUNBYN ITPP047 thermal printer model

Usage

Basic Example

#include "munbyn_printer.h"

int main() {
    // Open MUNBYN ITPP047 printer connection
    MunbynPrinter printer = munbyn_open("/dev/ttyUSB0", 9600);
    if (!printer) {
        printf("Failed to open MUNBYN ITPP047 printer\n");
        return 1;
    }
    
    // Print some text
    munbyn_print_text(printer, "Hello, World!\n");
    
    // Print a barcode
    munbyn_print_barcode_code128(printer, "1234567890", 50, 2, 1);
    
    // Feed and cut
    munbyn_feed_lines(printer, 3);
    munbyn_cut_paper(printer);
    
    // Close connection
    munbyn_close(printer);
    return 0;
}

Compiling Your Programs

After installation:

gcc -o myprogram myprogram.c -lmunbyn

Or if using the library locally:

gcc -Isrc -o myprogram myprogram.c -Lbuild/lib -lmunbyn

Examples

The examples/ directory contains several demonstration programs:

• example.c: Basic printing and barcode operations
• text_formatting_example.c: Text styling, fonts, and alignment
• barcode_example.c: Various barcode types and configurations
• charset_example.c: Character set and codepage examples
• feed_test.c: Paper feeding and cutting operations

Run the examples:

make examples
./build/examples/example
./build/examples/barcode_example
# etc.
