Raspberry Pi Photobooth Printing

Question

我已经建立了this photobooth，我正在努力弄清楚我需要添加到脚本中的代码才能打印出每张照片的副本。我已经使用杯子将我的打印机映射到覆盆子pi。

Here是与脚本github。

谢谢！

首先，您将需要pycups。那么这个代码应该工作，但我无法测试它：

# 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) 

图片是im，这是在line 168创建。只需将该代码粘贴到该行下面即可。

欲了解更多详情，您可以在boothcam.py#L99找到snap方法。

这是一个脚本，我成功地测试了：

#!/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)
