closing an instance of acrobat reader from command line

I am using the following cmd to print the pdf:

acroRD32.exe /t "file1.pdf" "printerName"

Everything works f开发者_运维问答ine but one window pops up. Can anybody help me to disable it. I tried with various options included in this question but cannot succeed.

Any help is appreciated.

Why even use Acrobat at all? This class that print silently for you without any executables or even a printer setup:

Sample Usage:
bool isPrinted = BatchPrint.PrintBinaryFile("file path", "Printer IP Address", "Queue Name", "User");

You cannot close the last open Acrobat window through the command line. From ancient history of programming scripts for Acrobat, I believe that there is no way to do this in an Acrobat script, either.

But you can close Acrobat from the command line, though it is a bit convoluted. For a pure MSDOS method for most Windows systems, create two files: called.bat and caller.bat.

caller.bat:

REM call the batch file that runs the program:
start "ProgramRunner" called.bat

REM wait 5 seconds -- if this closes Acrobat too soon, then increase the time:
ping 1.1.1.1 -n 1 -w 5000 >nul

REM kill the called program -- should be the program name that was started in called.bat:
REM (If the program does not close, type "taskkill /?" in the command line to see options.)
taskkill /F /IM acroRD32.exe

called.bat

"path\to\the\program\acroRD32.exe" /t "path\to\the\program\file1.pdf" "printerName"

exit

Note that you can write scripts in many programming languages that accomplish the same task more elegantly.

I successfully tested forking a delayed kill command before starting the print job.

start cmd /c "timeout 15 & taskkill /f /im acrord32.exe"
acroRD32.exe /t "file1.pdf" "printerName"
