Open parrallel problem

[Clement_2000]

Oh yes, thank you !!
It works with :

from tkinter import *

printer = open("/dev/lp0", "w")

win = Tk()
win.geometry("100x100")

def send(text):
    printer.write(str(text)) #Print text
    printer.write("\x0A\x0D") #Line feed and carriage return
    printer.flush()

textEntry = Entry(win)
textEntry.pack()

sendText = Button(win, text="Print", command=lambda:send(textEntry.get()))
sendText.pack()

win.mainloop()

printer.close()

THANK YOU SO MUCH !
