Python的无声模式：静默包与静默打印

def print_pdf(x):
    GHOSTSCRIPT_PATH = r'C:\workC\gs9.54.0\bin\gswin64c.exe'
    GSPRINT_PATH = r'C:\workC\Ghostgum\gsview\gsprint.exe'
    # YOU CAN PUT HERE THE NAME OF YOUR SPECIFIC PRINTER INSTEAD OF DEFAULT
    currentprinter = win32print.GetDefaultPrinter()
    print(x)
    win32api.ShellExecute(
        0, \
        'open', \
        GSPRINT_PATH, \
        '-ghostscript \
        "' + GHOSTSCRIPT_PATH + '"  \
        -printer \
        "' + currentprinter + '" \
        "'+ x +'" ', \
        '.', \
        0
    )

x:是需要打印PDF的绝对路径
需要安装ghostscript以及gsprint.
查找了很多个地方才发现gsprint原来是gsview的一个组件.特此说明,大家避免被坑.
