*I also tried Rotation but its still not working.*
*These are the preprocessing steps that i used:*
import cv2
import pytesseract
import numpy as np
from scipy import ndimage
img = cv2.imread('voucher.png')
img = cv2.bitwise_not(img)
img = cv2.resize(img, None, fx=1.2, fy=1.2, interpolation=cv2.INTER_CUBIC)
img = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
kernel = np.ones((1, 1), np.uint8)
img = cv2.dilate(img, kernel, iterations=1)
img = cv2.erode(img, kernel, iterations=1)
img = ndimage.rotate(img, -20)
cv2.imwrite("changed.png",img)
pytesseract.pytesseract.tesseract_cmd = r'C:\Program
Files\Tesseract-OCR\tesseract.exe'
print(pytesseract.image_to_string(img))
