我有一个PDF文档，我想用我的python应用程序打印它。
我在here (Print PDF document with python's win32print module?)尝试了解决方案，但是当我安装Ghostscript 9.15时，它是实际版本，它没有gsprint.exe
我使用它的方式是使用命令os.startfile('PDFfile.pdf', "print")，但它打开默认查看器（我的是Adobe Reader），打印后它仍然打开，试图用os.system("TASKKILL /F /IM AcroRD32.exe")杀死其他进程杀死其他打开窗户，我不想要它。
使用下一个命令，它也会打印，但它也会打开Adobe Reader
currentprinter = win32print.GetDefaultPrinter()
win32api.ShellExecute(0, "print", 'PDFfile.pdf', '/d:"%s"' % currentprinter, ".", 0)
我也见过this answer，但他们建议再次使用gsprint.exe
是否有人拥有gsprint.exe文件或任何其他解决方案？
注意：当我使用其他默认程序打开Chrome或Windows Reader等PDF文件时，我总是在执行'(31, 'ShellExecute', 'A device attached to the system is not functioning.')'或{{1}上面的命令时遇到异常使用[Error 1155] No application is associated with the specified file for this operation: 'PDFfile.pdf'命令

最后，经过几个小时的搜索正确的文件后，我找到了问题的答案。
您可以在HERE
下载GSPRINT您可以在HERE
下载Ghostscript GPL使用PC（Windows）中提取的文件，您可以使用此命令打印PDF
GHOSTSCRIPT_PATH = "C:\\path\\to\\GHOSTSCRIPT\\bin\\gswin32.exe"
GSPRINT_PATH = "C:\\path\\to\\GSPRINT\\gsprint.exe"
# YOU CAN PUT HERE THE NAME OF YOUR SPECIFIC PRINTER INSTEAD OF DEFAULT
currentprinter = win32print.GetDefaultPrinter()
win32api.ShellExecute(0, 'open', GSPRINT_PATH, '-ghostscript "'+GHOSTSCRIPT_PATH+'" -printer "'+currentprinter+'" "PDFFile.pdf"', '.', 0)
GhostScript也可以在官方页面HERE
中找到我找到了64位HERE
的gsprint.exe我希望这会有所帮助。

我知道这是一个古老的问题，但是如果有人在找，这是我如何解决它。
我在Windows 10 64位和python3-ghostscript库上使用python 3.8和gs9.52，可以使用pip install python3-ghostscript安装。我也在使用pypiwin32获取默认打印机名称，可以使用点pip install pypiwin32
这是工作脚本
import tempfile
import win32print
import locale
import ghostscript
import render_to_pdf
pdf = render_to_pdf('print/slip.html', context)
temp1 = tempfile.mktemp('.pdf')
f1 = open(temp1, 'ab')
f1.write(pdf)
f1.close()
args = [
"-dPrinted", "-dBATCH", "-dNOSAFER", "-dNOPAUSE", "-dNOPROMPT"
"-q",
"-dNumCopies#1",
"-sDEVICE#mswinpr2",
f'-sOutputFile#"%printer%{win32print.GetDefaultPrinter()}"',
f'"{temp1}"'
]
encoding = locale.getpreferredencoding()
args = [a.encode(encoding) for a in args]
ghostscript.Ghostscript(*args)
这里没有什么要注意的，我使用的是'＃'而不是'='，因为某些原因它不能与'='一起使用。
如果这不适用于您，请尝试将-sDEVICE开关更改为您的打印机类型，例如，当我使用 HP LaserJet 时，它提示我，因此我将-sDEVICE更改为Laserjet并成功了，您可以通过在终端上运行gs -h来获取设备列表
答案 2 :(得分：0)
这是一种在没有gsprint和win32api的情况下，在与python脚本相同的目录中静默打印pdf的方法。它允许更多的GhostScript自定义，例如选择宽度/高度等。
import os
import subprocess
import sys
if sys.platform == 'win32':
args = '"C:\\\\Program Files\\\\gs\\\\gs9.23\\\\bin\\\\gswin64c" ' \
'-sDEVICE=mswinpr2 ' \
'-dBATCH ' \
'-dNOPAUSE ' \
'-dFitPage ' \
'-sOutputFile="%printer%myPrinterName" '
ghostscript = args + os.path.join(os.getcwd(), 'myFile.pdf').replace('\\', '\\\\')
subprocess.call(ghostscript, shell=True)
如果您使用的是32位版本的GhostScript，则应使用gswin32c

如果要打印特定的页面和其他一些参数，则应在CMD的参数中指定它们，如下所示：

以下代码将阻止当前任务
for i in range(10):
currentprinter = win32print.GetDefaultPrinter()
win32api.ShellExecute(0, "print", 'PDFfile.pdf', '/d:"%s"' % currentprinter, ".", 0)
在打印帮助后杀死阅读器不会阻止当前任务
os.system("TASKKILL /F /IM AcroRD32.exe")
但是它也会关闭其他pdf文件。
如果不能使用gsprint，请使用acrobat命令
import win32print
import subprocess
import time
pdf_file = 'D:\d1\d1.pdf'
acrobat = 'C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\AcroRd32.exe'
name = win32print.GetDefaultPrinter()
cmd = '"{}" /n /h /s /o /t "{}" "{}"'.format(acrobat, pdf_file, name)
for i in range(10)):
proc = subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
它不会阻止当前任务并关闭其他pdf文件。

所以这不是完全无声的，但它会自动关闭对话框并无论如何打印，而且对硒有一种奇怪的依赖，你本身不会期望，但这实际上对我有用，因为我在世界上不允许我下载 ghostscript 也不能下载 adobe 的 pdf 阅读器。我认为它可能会帮助其他人，某个地方，某个地方，某个时间......
