Free restaurant software

Today, I’m adding to the list of my free programs a software for managing restaurants. This program will allow you to register tables, payment methods, dishes (with photos), modify the currency, language, generate a printable menu, view the order, and even allow self-service for customers.

Moreover, the free restaurant system I’ve created is compatible with Android (Termux), Windows, Linux, and Raspberry Pi. In fact, it is compatible with any platform where C and Go can compile, including an internet server.

Throughout this post, I will show you all the features of this program, which is the largest one I’ve created so far, not because of its complexity but because of all the new things it offers, such as the installer, the multilingual section (with choice of locale and currency), ticket customization, logo, and dasboard.


Silent PDF Print with JavaScript and plugin

Today I am going to present you a plugin that I have just created. It is a plugin to print a PDF file silently, that is, without asking the user for confirmation.

This plugin exposes a REST API so that a PDF can be printed without confirmation using JavaScript. Just make an HTTP GET request to the plugin path sending the name of the PDF and the name of the printer.

The best thing about this is that you can use the virtual printers that Windows offers, in this way you can do your tests in an ecological way.

Throughout this post I will show you the documentation of the plugin and all the details of it, including how you can get it.


Windows – Print PDF from CMD with PDFtoPrinter

In this post I will show you how to print a PDF document from the Windows command line, terminal or CMD using the executable PDFtoPrinter.exe.

As you know, printing a PDF from the Windows terminal is not possible using the print command (since it only prints text files), since a translator is required to read the content of the PDF and send it to the printer.

It is precisely what this utility called PDFtoPrinter.exe does, and in this post I’ll show you how to use it.


Start program at Windows Startup

In this post I will show you how to make an executable open when Windows starts, adding its shortcut to a special directory called Startup folder.
