Printer is Non-Responsive #21
Description
I guess I somehow broke the connection to the printer (A40). After unsuccessful attempts to print PDF files (tried to convert them to Pillow images and printImage()) my printer doesn't even react to turning it off, it just stays on.
Steps...
Code: PDF-to-Image and printImage()
import subprocess
from pathlib import Path
from PIL import Image
from pdf2image import convert_from_path
import peripage
def get_mac_and_model():
print('Retrieving MAC and Peripage model...')
result = subprocess.run(['hcitool', 'scan'], capture_output=True)
raw_output = result.stdout.decode()
out = raw_output.replace('Scanning ...\n\t', '').split('\t')
mac = out[0].strip()
model = out[1].strip()
print(f'[{model}] on [{mac}] found')
return mac, model
mac, model = get_mac_and_model()
printer = peripage.Printer(mac, peripage.PrinterType.A40)
printer.connect()
printer.reset()
# Set print concentration
printer.setConcentration(1)
def print_pdf(file_path: Path) -> None:
# Convert to PDF-file to multiple images...
print('Converting a PDF-file into images...')
pages = convert_from_path(file_path, 200)
images_files = []
for count, page in enumerate(pages):
img_name = f'out_{count}.jpg'
page.save(img_name, 'JPEG')
images_files.append(img_name)
print(f'New PDF page converted: {img_name}')
# Print save images...
print('Printing images...')
for img_name in images_files:
with Image.open(img_name) as img:
printer.printlnASCII('NEW PAGE')
printer.printImage(img)
printer.printBreak(100)
print(f'Printed: {img}')
if __name__ == '__main__':
print_pdf(Path('local_file.pdf'))Printer Response
It started to use paper, not printing anything on it (before that, I successfully printed "HONK" from the README.md). So I've decided to turn it off by opening the cover (yes, I didn't read the instruction). It kind of worked, the printer stopped. However, it doesn't really work now.
Current State
Now I can't really use the printer. I've tried to install drivers on Win10 but the installer doesn't see the printer as well. None of my tries succeeded in bringing back the printer's functionality. I still see a green LED bear-face no matter what I do.
P.S. Strangely enough, Win10 gave me multiple power surge warnings when I was connecting the printer via a USB-hub. So I might accidentally kill the hub.
P.P.S. Bluetooth-pairing process works just fine on both, Ubuntu and Win10.
