Prerequisite: Tkinter, win32api
Python offers multiple options for developing GUI (Graphical User Interface). Out of all the GUI methods, tkinter is the most commonly used method. It is a standard Python interface to the Tk GUI toolkit shipped with Python. Python with tkinter is the fastest and easiest way to create GUI applications. Creating a GUI using tkinter is an easy task.
In this article, we will discuss how to print a hard copy in the printer using Tkinter.
Step-by-step Approach
- Make a Tkinter window.
- Add One Button.
- Open the file which you want to print using the askopenfilename() method in Tkinter.
- Print it using ShellExecute() method in win32api.
Create Normal Tkinter Window
Python3
# Import Required Library from tkinter import * # Create Tkinter Object root = Tk() # Set Title and geometry root.title('Print Hard Copies') root.geometry("200x200") # Make Button Button(root,text="Print FIle").pack() # Execute Tkinter root.mainloop() |
Output:
Methods Used
- askopenfilename: This method is used to open a given file.
filedialog.askopenfilename(mode=’r’, filetypes=[(‘any name you want to display’, ‘extension of file type’)])
- ShellExecute: It is used to execute shell commands of a system.
win32api.ShellExecute(hwnd, dir, bShow, op, file, params, **args)
hwnd: The handle of the parent window, or zero for no parent. This window receives associate message boxes an application produces (for example, for error reporting).
op: The operation to perform. is also “open”, “print”, or None, that defaults to “open”.
file: The name of the file to open.
params: The parameters to pass, if the file name contains associate viable. ought to be None for a document file.
dir: The initial directory for the application.
bShow: Specifies whether the appliance is shown once it’s opened. If the lpszFile parameter specifies a document file, this parameter is zero.
Below is the Implementation
Python3
# Import Required Library from tkinter import *import win32api from tkinter import filedialog # Create Tkinter Object root = Tk() # Set Title and geometry root.title('Print Hard Copies') root.geometry("200x200") # Print File Function def print_file(): # Ask for file (Which you want to print) file_to_print = filedialog.askopenfilename( initialdir="/", title="Select file", filetypes=(("Text files", "*.txt"), ("all files", "*.*"))) if file_to_print: # Print Hard Copy of File win32api.ShellExecute(0, "print", file_to_print, None, ".", 0) # Make Button Button(root, text="Print FIle", command=print_file).pack() # Execute Tkinter root.mainloop() |
On execution of the above python script, a tkinter window will pop up which will require to upload a text file, after uploading, the text file gets printed.
