SBPL module for remote printing

Project description

SBPL

SBPL module for remote printing

Summary

This provides the function of remote printing directly to the printer existing on your LAN by using SBPL (SATO Barcode Printer Language) provided by SATO Corp.

This enables arbitrary label cutting which can not be controlled by a normal Windows printer.

This module has a function to print TrueType fonts using Freetype. Execute method ttf_write().

This module is a prototype and may not satisfy your work, but since it is Pure Python, you can add and change features yourself.

Install

$ pip install sbpl

Usage

from sbpl import *

comm = SG412R_Status5()
with comm.open("192.168.0.251", 1024):
    comm.prepare()

    # generate label...
    gen = LabelGenerator()
    with gen.packet_for_with():
        with gen.page_for_with():
            gen.set_label_size((1000, 3000))
            gen.rotate_270()
            gen.pos((260, 930))
            gen.codebar(("0004693003005000", 3, 100))
            gen.pos((160, 1000))
            gen.expansion((1,1))
            gen.bold_text("0004693003005000")
            gen.print()
    
    comm.send(gen.to_bytes())
    comm.finish()

You can describe print contents in JSON format and can specify them all together.
