I\'m trying to print a pdf file from Python with module win32print
but the only way I can print success is a text.
hPrinter = win32print.OpenPri
I'd like a solution which is able to print about 100 pdf files daily every about 200 pages long. Files are stored in certain directory.
import win32api
import win32print
from glob import glob
# A List containing the system printers
all_printers = [printer[2] for printer in win32print.EnumPrinters(2)]
# Ask the user to select a printer
printer_num = int(input("Choose a printer:\n"+"\n".join([f"{n} {p}" for n, p in enumerate(all_printers)])+"\n"))
# set the default printer
win32print.SetDefaultPrinter(all_printers[printer_num])
pdf_dir = "D:/path/to/pdf_dir/**/*"
for f in glob(pdf_dir, recursive=True):
win32api.ShellExecute(0, "print", f, None, ".", 0)
input("press any key to exit")
Notes:
While not direct answer to the question, I couldn't resist the opportunity to make a GUI using tkinter
. It can be easily changed to select a dir - and all the files inside - instead of a single file.

PS: I may not win the bounty, but I certainly enjoyed making the GUI. tkinter
layout was the hardest part!
You can try
win32print.SetDefaultPrinter("\\\\Server\Printer")
This method accepts a String, not the printer object you tried to pass it.
This is the code I have used and it works correctly.
name = win32print.GetDefaultPrinter() # verify that it matches with the name of your printer
printdefaults = {"DesiredAccess": win32print.PRINTER_ALL_ACCESS} # Doesn't work with PRINTER_ACCESS_USE
handle = win32print.OpenPrinter(name, printdefaults)
level = 2
attributes = win32print.GetPrinter(handle, level)
#attributes['pDevMode'].Duplex = 1 #no flip
#attributes['pDevMode'].Duplex = 2 #flip up
attributes['pDevMode'].Duplex = 3 #flip over
win32print.SetPrinter(handle, level, attributes, 0)
win32print.GetPrinter(handle, level)['pDevMode'].Duplex
win32api.ShellExecute(0,'print','manual1.pdf','.','/manualstoprint',0)
