How to merge and combine PDF files using Python language?

June 14, 2020June 15, 2020

In this tutorial I will show you how to merge and combine two or more PDF files into one PDF file using Python 3.

VeryUtils PythonPDF Library is a Python Library for splitting and merging the pages of PDF and PDF/A conform documents with practical additional functions. It can process multiple input and output documents simultaneously. PDF Merge Split is available as shell tool for batch processing with the command line and as API to be integrated with Python, PHP, C#, Visual Basic, Java or C/C++.

PythonPDF Library can be purchased on this web page,

https://veryutils.com/pythonpdf-library-source-code

after you purchase it, you will get a download URL to the latest version of PythonPDF Library, please download and unzip it to a folder, such as,

D:\downloads\python-pdfrw

before you use it, please set the main path to "PYTHONPATH" first, for example,

set PYTHONPATH=D:\downloads\python-pdfrw

then please go to "examples" folder, run following command line to test the PDF Merging function,

python cat.py testcmd.pdf watermark.pdf

You will get a merged PDF file after a few seconds, in the following screenshot, the pages #1-#32 are come from first PDF file, the pages #33-#43 are come from second PDF file,

The following is the Python source code of cat.py file,

--------------------------------------------------
import sys
import os

from pdfrw import PdfReader, PdfWriter, IndirectPdfDict

inputs = sys.argv[1:]
assert inputs
outfn = 'cat.' + os.path.basename(inputs[0])

writer = PdfWriter()
for inpfn in inputs:
writer.addpages(PdfReader(inpfn).pages)

writer.trailer.Info = IndirectPdfDict(
    Title='your title goes here',
    Author='your name goes here',
    Subject='what is it all about?',
    Creator='some script goes here',
)
writer.write(outfn)
--------------------------------------------------

This cat.py file demonstrates two features:

1) Concatenating multiple input PDFs.
2) Adding metadata to the PDF.

How to use PHP Folder Watcher to monitor a folder and print JPG files to a certain tray of the printer?

June 11, 2020

Hi David,

Quick question about PHP Folder Watcher. Running PHP on Windows via Xampp. All I need is a watcher to see new .jpg files and send them to a local printer. But some files I need to send to a certain tray of the printer (i.e. Legal or Letter size). If your script doesn't already do that, do you think it's something I can modify? I know ONLY PHP. Also the printer is NOT the default printer and is shared on a network. Is that an issue?

Thanks so much!

Hello,

Thanks for your message, PHP Folder Watcher is just a "watcher" to some folders, if you need to print JPG files to a certain tray of the printer, you need to use following product,

https://veryutils.com/pdf-print-command-line

You may login and download the trial version for free.

PHP Folder Watcher can be purchased on this web page,

https://veryutils.com/php-folder-watcher

PDFPrint Command Line is a Windows Command Line application which can be used to print PDF and Image files to a certain tray of the printer (i.e. Legal or Letter size), the network printer is not an issue, you can use PDFPrint Command Line to print PDF and Image files to both local and network printers without any problem.

-listbins                        : list bins/trays of a printer
-listjobs                        : list print jobs in printer's queue
-listall                         : list printers, ports, monitors etc.
-listpapers                      : list supported papers from a printer.
-chgbin <int>                    : change bin/tray for printer by number
-papersource <string>            : change bin/tray for printer by name
-settraytopclfile <string>       : set tray to PCL file directly, only work when '-papersource' used

for example, you may call following command lines from PHP Folder Watcher to print PDF or JPG files to special tray of the printer,

   pdfprint.exe -listbins -printer "docPrint"
   pdfprint.exe -listpapers -printer "docPrint"
   pdfprint.exe -chgbin 15 -printer "docPrint" C:\input.pdf
   pdfprint.exe -papersource "auto" -printer "docPrint" C:\input.pdf
   pdfprint.exe -papersource "Tray 1" -printer "docPrint" C:\input.pdf
   pdfprint.exe -papersource "Manual Feed" -printer "docPrint" C:\input.pdf
   pdfprint.exe -papersource "Media Tray" -printer "docPrint" C:\input.pdf
   pdfprint.exe -papersource "Tray 3" -settraytopclfile C:\test.pcl
   pdfprint.exe -papersource "auto" -printer "docPrint" C:\input.jpg
   pdfprint.exe -papersource "Tray 1" -printer "docPrint" C:\input.png
   pdfprint.exe -papersource "Tray 2" -printer "docPrint" C:\input.tif
   pdfprint.exe -papersource "Tray 3" -printer "docPrint" C:\input.doc
   pdfprint.exe -papersource "Tray 4" -printer "docPrint" C:\input.docx

In the PHP Folder Watcher script, you can modify RunExternalEXE() function to call the PDFPrint.exe application, for example,

function PrintFile($strInFile)
{
    $strCurrentFolder = dirname(__FILE__);
    $strExeFile = $strCurrentFolder . '/pdfprint/pdfprint.exe';
    $strCmd = "\"$strExeFile\" -papersource \"Tray 4\" \"$strInFile\"";
    MyEcho(__FILE__, __LINE__, '', $strCmd);
    $strRawOutput = shell_exec($strCmd);
    MyEcho(__FILE__, __LINE__, '', "<pre>$strRawOutput</pre><br>");
    return $strRawOutput;
}

function RunExternalEXE($strInFile, $strInRootFolder, $strOutFolder, $strBackupFolder)
{
MyEcho(__FILE__, __LINE__, '', "[RunExternalEXE] $strInFile => $strOutFolder");
PrintFile($strInFile);
}
