log@breadcube:~/public_html/week8$
At this point the script was like:
from escpos.printer import File
import time
import os
import math
printername = "/dev/usb/lp1"
printerwidth = 64
wavelength = 10
for i in range(0,64):
# os.system('echo "' + str(i) + '" > /dev/usb/lp0')
# iprinter.text(str(i))
pos = 1+math.sin(i/wavelength)
# print(pos)
if (i%8 == 0) or (i%16 == 10):
print(" "*int(pos*printerwidth) + "%")
# os.system('echo "' + " "*int(pos*printerwidth) + '%" > ' + printer0name)
elif i%8 == 4:
print(" "*int(pos*printerwidth) + "~")
# os.system('echo "' + " "*int(pos*printerwidth) + '~" > '+ printer0name)
else:
print(" "*int(pos*printerwidth) + "*")
# os.system('echo "' + " "*int(pos*printerwidth) + '*" > '+ printer0name)
time.sleep(0.125)
# iprinter.close()
So uncomment the lines and then
