Posted on

jpdfkit is a PDF conversion and form utility for Windows, Mac and Linux systems. You can use this command line software to combine PDFs, remove PDF pages, split PDF PDFs, and fill in PDF forms with this handy Linux command line easily.

Business peoples are deal with huge numbers of PDF files every day. The PDF format is popular because it contains processed PostScript code. PostScript is the printer language of modern printers, so publishers often publish digital versions of books in PDF format, and they invest time and effort in producing PDF files for printing. But PDF is not an editable format, and while some reverse processing is possible, it should be the last stop for digital data before it is sent to the printer. Even so, sometimes you need to make adjustments to your PDF files, VeryUtils jpdfkit tool is the most efficient PDF command line tool.

The trial version of jpdfkit can be downloaded from this web page,

https://veryutils.com/java-pdf-toolkit-jpdfkit

jpdfkit Command Line software highlight features:
* Fill forms, either from a XFDF/FDF file or from a data array (UTF-8 safe for unflattened forms).
* Create XFDF or FDF files from PHP arrays (UTF-8 safe!).
* Create FDF files from filled PDF forms.
* Combine pages from several PDF files into a new PDF file.
* Split a PDF into one file per page.
* Add background or overlay PDFs.
* Read out meta data about PDF and form fields.
* Set passwords and permissions to PDF files.
* Remove passwords from PDF files.

jpdfkit Command Syntax
The structure of a valid jpdfkit command follows a pattern, but there's a lot of flexibility in what's in the pattern. The syntax is a little unusual because it doesn't use traditional-style terminal options, but with practice, it's not too difficult to remember.

jpdfkit: The alias to call the command
input file: The PDF you want to modify
action: What you want to do to the input file
output: Where you want to save your modified PDF file

jpdfkit encrypted PDF file can’t be opened because permission denied problem in SUSE and CentOS Linux systems

Posted on

Find if permission denied errors are caused by SELinux for VeryUtils Java PDF Toolkit (jpdfkit) software.

VeryUtils Java PDF Toolkit (jpdfkit) can run on Linux systems, VeryUtils Java PDF Toolkit (jpdfkit) can be downloaded from following web page,

https://veryutils.com/java-pdf-toolkit-jpdfkit

However, we recently noticed an issue where we used the following command line to encrypt PDF files on SUSE Linux system,

java -jar /Encrypt-PDF/jpdfkit_1/jpdfkit.jar /Encrypt-PDF/jpdfkit_1/Manual.pdf output /Encrypt-PDF/jpdfkit_1/Manual-output.pdf owner_pw 123 user_pw 456 encrypt_128bit allow printing

The encrypted PDF file couldn't be opened because permission denied problem, even if we tried to copy encrypted PDF file to another file, we still encounter permission denied problem,

cp /Encrypt-PDF/jpdfkit_1/Manual-output.pdf /Encrypt-PDF/jpdfkit_1/Manual-output2.pdf

After we researched this problem for some days, we sure this problem caused by "SELinux" in Linux system, here is the solution.

SELinux, short for Security Enhanced Linux, is a Linux security module that is part of many Linux server distributions. While SELinux increases server security (despite being created by NSA), it often results in some unexpected access/permission denied errors.

If you get one of such errors on a server with SELinux enabled, and there are no obvious file permission issues, you should check if the issue is caused by SELinux. To check the status of SELinux, run:

sestatus

You should get something like this:

SELinux status: enabled
SELinuxfs mount: /sys/fs/selinux
SELinux root directory: /etc/selinux
Loaded policy name: targeted
Current mode: enforcing
Mode from config file: enforcing
Policy MLS status: enabled
Policy deny_unknown status: allowed
Max kernel policy version: 28

"Current mode: enforcing" indicates that SELinux is running.

image

To temporary disable SELinux, run:

setenforce 0

If this resolves the problem, and you no longer get "permission denied" errors, it means the issue was caused by SELinux. Re-enable it with setenforce 1 and try to find the root cause.

To help with troubleshooting, you can check SELinux log files located in /var/log/audit/audit.log

Very often, the issue is caused by incorrect security context (also called security label) assigned to the affected files or folders. To view security context that SELinux has applied to files or folders, run one of the following commands (they all display security contexts, just in different formats):

ls -Z or ls --context
ls --lcontext
ls --scontext

To modify the security context, you can use chcon command, i.e:

chcon -R -t httpd_sys_content_t /www/sites

httpd_sys_content_t - Apache Read-Only access
httpd_sys_rw_content_t - Apache Read/Write access
httpd_log_t - Apache log files
httpd_cache_t - Apache caching

or use reference directory:

chcon -R --reference=/var/www/html /www/sites

Capture Printed Documents and Save them to Cloud based MySQL database

Posted on

I need to create a software (preferably IN DELPHI 10.x) that monitors printers and looks for receipts and invoices. It should allow me to configure different businesses and everything should be saved to my hosted cloud based MySQL database.

Now, the critical thing is this: when each business is first configured, the system should allow me to print an initial invoice/receipt which is captured. It should then allow me to define certain fields on the invoice: Invoice Number, Date, Item Number, Description, Qty, price, Discount (if applicable) and total, for each line of the invoice/receipt. It should also allow me to define the total of the invoice and payment. All this will be stored in the cloud database.

After this, the software should run automatically in the system tray, and access be password protected. This config is also stored in the cloud. Whenever anyone prints any invoice/receipt, the software should capture the details and store it in the cloud database.

The final part of the software is the admin part which is installed on a different system. The admin part will allow me to configure each business, and run several reports, which will show details of transactions printed during requested periods, with the option to drill down to the individual invoice details. I should also be able to setup different users to access the admin part with various levels of access.

How can I intercept and capture the content’s of a window’s spool file, and convert this SPL file to PDF file?

Posted on

I have files being printed from a client's computer and would like to intercept and archive the printed file as text or pdf. The client will most likely be using a specific software to print and I do not want to integrate with each of the different software's any client could be using.

Is there a way to intercept the content's of the print job, whether programmatically (python's win32print or wmi, c#, etc) or by converting the spool file (.spl & .shd) that is created in the C:\Windows\system32\spool\PRINTERS directory during print queuing.

Customer
------------------------------------------
All print files in Windows are kept in the folder C:\Windows\System32\spool\PRINTERS, which requires Administrator permissions to access.

The files are in the format of .SPL files, which require a viewer.

As intercepting these files while they are being printed is hard, you may instead ask Windows to keep them after printing, for you to copy afterward. This depends on your printer having the option of "Keep printed documents" in the printer Properties, usually in the Advanced tab.
