Python打印到/ dev/usb/lp0

Question

我想從我的python代碼打印到/dev/usb/lp0。在bash這很簡單：echo 'apple' >/dev/usb/lp0

我發現linemode，但這是行不通的。當我嘗試安裝它時，我收到了這些錯誤。

byte-compiling build/bdist.linux-x86_64/egg/linemode/renderers/xml.py to xml.pyc 
File "build/bdist.linux-x86_64/egg/linemode/renderers/xml.py", line 67 
def __init__(self, source, *, max_width=None, prelude=True): 
          ^
SyntaxError: invalid syntax 

如何從Python代碼打印到/dev/usb/lp0？

Answer 1

這是工作：

with open('/dev/usb/lp0', 'w') as printer: 
      printer.write("Line 1\n") 
      printer.write("Line 2\n")
