python-StarTSPImage

Print from Python to Star TSP100/143/650/654

Star TSP100/TSP143 printers do not have any font sets etc on board the printer, so any data being sent directly to the printer must first be converted into a raster image using the appropriate graphic mode commands. (Star do provide a driver that emulates Star line mode commands, but we can't use this if we want to interact directly with the printer)

This project will take an image file (Either as a PIL image, or from file on disk), scale it to the appropriate width for the printer, and then create a binary output of the graphic mode raster commands, which then can be sent directly to the device. You could use Pillow or imgkit to programmatically build images.

For more detailed reading, you can find the graphic mode command manual at: http://www.starasia.com/Download/Manual/star_graphic_cm_en.pdf

Installing

pip install StarTSPImage

Examples

Print a file from disk:

import StarTSPImage

raster = StarTSPImage.imageFileToRaster('file.bmp', cut=True)

printer = open('/dev/usb/lp0', 'wb')
printer.write(raster)

Create a PIL image and print:

import StarTSPImage
from PIL import Image, ImageDraw

image = Image.new('RGB', (500, 500), color='White')
draw = ImageDraw.Draw(image)
draw.ellipse((0, 0, 500, 500), fill='Black')
draw.ellipse((10, 10, 490, 490), fill='White')

raster = StarTSPImage.imageToRaster(image, cut=True)

printer = open('/dev/usb/lp0', "wb")
printer.write(raster)

Search for Star printer via vendor/product ID, then create a PIL image and print:

import StarTSPImage
import usb.core
from PIL import Image, ImageDraw

vendorId = 0x0519   # Star
productId = 0x0003  # TSP143

dev = usb.core.find(idVendor=vendorId, idProduct=productId)

if dev:

    print('Found:', usb.util.get_string(dev, dev.iProduct))

    # Build PIL image
    image = Image.new('RGB', (500, 500), color='White')
    draw = ImageDraw.Draw(image)
    draw.ellipse((0, 0, 500, 500), fill='Black')
    draw.ellipse((10, 10, 490, 490), fill='White')

    # Create raster for Star
    raster = StarTSPImage.imageToRaster(image, cut=True)

    # Send to device using endpoint 2 (OUT)
    dev.write(2, raster)

else:
    print('Could not find device')

Long printing: You might need to break the raster image up into chunks, and then send to the printer...

import funcy
for bytechunk in list(funcy.chunks(32*1024, raster)): 
    dev.write(2, bytechunk)
