Print image using win32print and PIL

print_with_win32print.py

import win32print
import win32ui
from PIL import Image, ImageWin

PHYSICALWIDTH = 110
PHYSICALHEIGHT = 111

printer_name = win32print.GetDefaultPrinter ()
file_name = "new.jpg"

hDC = win32ui.CreateDC ()
hDC.CreatePrinterDC (printer_name)
printer_size = hDC.GetDeviceCaps (PHYSICALWIDTH), hDC.GetDeviceCaps (PHYSICALHEIGHT)

bmp = Image.open (file_name)
if bmp.size[0] < bmp.size[1]:
  bmp = bmp.rotate (90)

hDC.StartDoc (file_name)
hDC.StartPage ()

dib = ImageWin.Dib (bmp)
dib.draw (hDC.GetHandleOutput (), (0,0,printer_size[0],printer_size[1]))

hDC.EndPage ()
hDC.EndDoc ()
hDC.DeleteDC ()

You legend. Thankyou !

hi, why the printed file is black background? how to solve it

Thank you!!

Please i need your help: i have this code, it's printing fine but it's not cutting the paper:

try:
    printer_name = "EPSON T20III"
    raw_data = bytes(recipt.text, "utf-8")

    drivers = win32print.EnumPrinterDrivers(None, None, 2)
    hPrinter = win32print.OpenPrinter(printer_name)
    printer_info = win32print.GetPrinter(hPrinter, 2)
    for driver in drivers:
        if driver["Name"] == printer_info["pDriverName"]:
            printer_driver = driver
   
    raw_type = "XPS_PASS" if printer_driver["Version"] == 4 else "RAW"
    try:
        hJob = win32print.StartDocPrinter(hPrinter, 1, ("test of raw data", None, raw_type))
        try:
            win32print.StartPagePrinter(hPrinter)
            win32print.WritePrinter(hPrinter, raw_data)
            win32print.EndPagePrinter(hPrinter)
    
        except Exception as e:
            message.warning(request, f"Error! {e}")
        finally:
            win32print.EndDocPrinter(hPrinter)  
    except Exception as e:
        message.warning(request, f'Error! {e}')
    finally:
        win32print.ClosePrinter(hPrinter)
except Exception as e:
    message.warning(request, f"Error printing! {e}")

here is the problem in full detail:

Por favor, necesito su ayuda: tengo este código, se está imprimiendo bien pero no está cortando el papel:

try:
    printer_name = "EPSON T20III"
    raw_data = bytes(recipt.text, "utf-8")

    drivers = win32print.EnumPrinterDrivers(None, None, 2)
    hPrinter = win32print.OpenPrinter(printer_name)
    printer_info = win32print.GetPrinter(hPrinter, 2)
    for driver in drivers:
        if driver["Name"] == printer_info["pDriverName"]:
            printer_driver = driver
   
    raw_type = "XPS_PASS" if printer_driver["Version"] == 4 else "RAW"
    try:
        hJob = win32print.StartDocPrinter(hPrinter, 1, ("test of raw data", None, raw_type))
        try:
            win32print.StartPagePrinter(hPrinter)
            win32print.WritePrinter(hPrinter, raw_data)
            win32print.EndPagePrinter(hPrinter)
    
        except Exception as e:
            message.warning(request, f"Error! {e}")
        finally:
            win32print.EndDocPrinter(hPrinter)  
    except Exception as e:
        message.warning(request, f'Error! {e}')
    finally:
        win32print.ClosePrinter(hPrinter)
except Exception as e:
    message.warning(request, f"Error printing! {e}")

Aquí está el problema con todo detalle:

win32print.WritePrinter(hPrinter, raw_data + b'\n\x1D\x56\x42\x10')
solucion b'\n\x1D\x56\x42\x10')

Thank you so much!
