Raspberry Pi Photobooth Printing

Question

我已經建立了this photobooth，我正在努力弄清楚我需要添加到腳本中的代碼才能打印出每張照片的副本。我已經使用杯子將我的打印機映射到覆盆子pi。

Here是與腳本github。

謝謝！

Answer 1

首先，您將需要pycups。那麼這個代碼應該工作，但我無法測試它：

# Set up CUPS 
conn = cups.Connection() 
printers = conn.getPrinters() 
printer_name = printers.keys()[0] 
cups.setUser('pi') 

# Save the picture to a temporary file for printing 
from tempfile import mktemp 
output = mktemp(prefix='jpg') 
im.save(output, format='jpeg') 

# Send the picture to the printer 
print_id = conn.printFile(printer_name, output, "Photo Booth", {}) 

# Wait until the job finishes 
from time import sleep 
while conn.getJobs().get(print_id, None): 
    sleep(1) 

圖片是im，這是在line 168創建。只需將該代碼粘貼到該行下面即可。

欲瞭解更多詳情，您可以在boothcam.py#L99找到snap方法。

這是一個腳本，我成功地測試了：

#!/usr/bin/env python 
# coding: utf-8 

import cups 
import Image 
from tempfile import mktemp 
from time import sleep 


# Set up CUPS 
conn = cups.Connection() 
printers = conn.getPrinters() 
printer_name = printers.keys()[0] 
cups.setUser('tiger-222') 

# Image (code taken from boothcam.py) 
im = Image.new('RGBA', (683, 384)) 
im.paste(Image.open('test.jpg').resize((683, 384)), (0, 0, 683, 384)) 

# Save data to a temporary file 
output = mktemp(prefix='jpg') 
im.save(output, format='jpeg') 

# Send the picture to the printer 
print_id = conn.printFile(printer_name, output, "Photo Booth", {}) 
# Wait until the job finishes 
while conn.getJobs().get(print_id, None): 
    sleep(1) 
unlink(output)
