Python silent print PDF to specific printer

Question

I have a PDF document and I want to print it with my python app.

I have tried the solution in here (Print PDF document with python's win32print module?) but when I install Ghostscript 9.15 that is the actual version, it has no gsprint.exe

The way I am using that works is with the command os.startfile('PDFfile.pdf', "print") but it opens default viewer (mine is Adobe Reader) and after printing it stills open, trying to kill the process with os.system("TASKKILL /F /IM AcroRD32.exe") kills other opened windows and I dont want it.

With the next command, it also prints, but it let the Adobe Reader opened too

currentprinter = win32print.GetDefaultPrinter()
win32api.ShellExecute(0, "print", 'PDFfile.pdf', '/d:"%s"' % currentprinter, ".", 0)

I have seen this answer too but they recommend using gsprint.exe again

Anybody has the gsprint.exe file or any other solution?.

NOTE: When I used another default program to open PDF files like Chrome or Windows Reader, I always get an Exception in the execution of the commands above '(31, 'ShellExecute', 'A device attached to the system is not functioning.')' or [Error 1155] No application is associated with the specified file for this operation: 'PDFfile.pdf' with the startfile command

Answer 1

If you want to print specific pages and some other parameters, you should specify them in the parameters of gsprint as follows:

import win32print
import win32api

GHOSTSCRIPT_PATH = "C:\\path\\to\\GHOSTSCRIPT\\bin\\gswin32.exe"
GSPRINT_PATH = "C:\\path\\to\\GSPRINT\\gsprint.exe"

params = '-ghostscript "'+ GHOSTSCRIPT_PATH  +'" -printer "'+currentprinter+'" -from 1 -to 3 -landscape -copies 1 "1.pdf "'
print(params)

win32api.ShellExecute(0, 'open', GSPRINT_PATH, params, '.',0)

Answer 2

Here's a way to silently print a pdf in the same directory as your python script without gsprint and without win32api. It allows for more GhostScript customization like choosing width/height, etc.

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)

If you're using the 32 bit version of GhostScript then you would use gswin32c

Answer 3

Finally after hours and hours of searching for the right files, i have found the answer to my problem.

You can download the GSPRINT in HERE

You can download the Ghostscript GPL in HERE

With this extracted files in your PC (Windows) you can print your PDF with this command

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)

The GhostScript can also be found in the Official page HERE

I found the gsprint.exe for 64bits HERE

I hope this helps.

The following code will block the current task

for i in range(10):
    currentprinter = win32print.GetDefaultPrinter()
    win32api.ShellExecute(0, "print", 'PDFfile.pdf', '/d:"%s"' % currentprinter, ".", 0)

and killing the reader after printing help won't block the current task

os.system("TASKKILL /F /IM AcroRD32.exe") 

but it will close other pdf files too.

If you can't use gsprint, use the acrobat command

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)

It won't block the current task and close the other pdf files.
