Print The Receipt On Thermal Printer Python

i am creating a inventory system on python.i need genterating print recipt after all sales done.when i click save button.i have using mysql database. it has sales and sales product

Solution 1:

Here is how i think you should proceed with the reciept.

from tkinter import *

root = Tk()

defreciept():
    top = Toplevel()
    price1 = 3000
    qty1 = 3
    total1 = price1*qty1

    price2 = 5000
    qty2 = 4
    total2 = price1*qty2

    l = Label(top,text='---------RECIEPT----------')
    l.pack()
    heading = Label(top,text='PRICE\tQTY\tTOTAL')
    heading.pack()

    item1 = Label(top,text=f'{price1}\t{qty1}\t{total1}')
    item1.pack()

    item2 = Label(top,text=f'{price2}\t{qty2}\t{total2}')
    item2.pack()

b = Button(root,text='Print reciept',command=reciept)
b.pack(padx=10,pady=10)
root.mainloop()

The \t will add 4 spaces to the end of the letter.

You can replace prices with your e1.get() and all.

You can also use grid() here but it might be cumbersome and takes more lines.

Hope you got an idea.
