Print.js

A tiny javascript library to help printing from the web.

PDF Printing

Print.js was primarily written to help us print PDF files directly within our apps, without leaving the interface, and no use of embeds. For unique situations where there is no need for users to open or download the PDF files, and instead, they just need to print them.

One scenario where this is useful, for example, is when users request to print reports that are generated on the server side. These reports are sent back as PDF files. There is no need to open these files before printing them. Print.js offers a quick way to print these files within our apps.

PDF files must be served from the same domain as your app is hosted under. Print.js uses iframe to load files before printing them, therefore, it is limited by the Same Origin Policy. This helps preventing Cross-site scripting (XSS) attacks.

Example

Add a button to print a PDF file located on your hosting server:

For large files, you can show a message to the user when loading files.

Print Large PDF ( 5mb file ) Print Extra Large PDF ( 16mb file )

The library supports base64 PDF printing:

HTML Printing

Sometimes we just want to print selected parts of a HTML page, and that can be tricky. With Print.js, we can easily pass the id of the element that we want to print. The element can be of any tag, as long it has a unique id. The library will try to print it very close to how it looks on screen, and at the same time, it will create a printer friendly format for it.

Example

Add a print button to a HTML form:

Print.js accepts an object with arguments. Let’s print the form again, but now we will add a header to the page:

Print Form with Header

Image Printing

Print.js can be used to quickly print any image on your page, by passing the image url. This can be useful when you have multiple images on the screen, using a low resolution version of the images. When users try to print the selected image, you can pass the high resolution url to Print.js.

Example

Load images on your page with just the necessary resolution you need on screen:

Printing an HTML document in Windows using C/C++?

I am trying to crate an application for Microsoft Windows in C/C++. The goal of the application is to take a text file as input, parse the text file and generate the output in form of an HTML file.

Then it prints the generated HTML file using a printer attached to the computer.

Everything is simple but printing. The problem is that I don’t know how to control printer to do the printing job, whether it’s an HTML document or any other.

I searched the forum and internet for a solution but here are my problems:

• I don’t know much about Windows programming since I come from Linux background.
• I have never used Visual C++ compiler so I had a little trouble understanding how things were going with it. (I have only used GCC/G++).

What I would like to know is whether there is any API available that I can use directly with my MinGW compiler. Or if there is any other method I could learn how to do this using Windows API supplied with Visual C++ compiler (which I suppose comes with Visual Studios in Windows).

Edit: I was also wondering if there was any way to print the file directly to the printer avoiding the popups every time a printing job is done. The application I am working on does a lot of printing jobs, so if it was possible to avoid those popping dialogs which ask user to select a printing device by automatically checking for available printing devices and choosing one as default.

Printing

There may be times in which your web site or application would like to improve the user’s experience when printing content. There are a number of possible scenarios:

• You wish to adjust layout to take advantage of the size and shape of the paper.
• You wish to use different styles to enhance the appearance of your content on paper.
• You wish to use higher resolution images for a better result.
• You want to adjust the user experience of printing, such as presenting a specially-formatted version of your content before printing begins.

There may be other cases in which you want to manage the printing process, but these are some of the most common scenarios. This article provides tips and techniques for helping your web content print better.

Detecting print requests

Some browsers (including Firefox 6 and later and Internet Explorer) send beforeprint and afterprint events to let content determine when printing may have occurred. You can use this to adjust the user interface presented during printing (such as by displaying or hiding user interface elements during the print process).

Examples

Here are some common examples.

If you want to be able to automatically close a popup window (for example, the printer-friendly version of a document) after the user prints its contents, you can use code like this:

Install a printer in Windows 10

When you connect a printer to your PC or add a new printer to your home network, you can usually start printing right away. Windows 10 supports most printers, so you probably won’t have to install special printer software. Additional printer drivers and support might be available if you update Windows 10.

Note: If your PC is running Windows 10 S, some printers might not work with it, or they might have limited functionality. For more info, see Device support on Windows 10 S.

If your printer is on and connected to the network, Windows should find it easily. Available printers can include all printers on a network, such as Bluetooth and wireless printers or printers that are plugged into another computer and shared on the network. You might need permission to install some printers.

Select the Start button, then select Settings > Devices > Printers & scanners.
Open Printers & scanners settings

Select Add a printer or scanner. Wait for it to find nearby printers, then choose the one you want to use, and select Add device.

If your printer isn’t in the list, select The printer that I want isn’t listed, and then follow the instructions to add it manually using one of the options.

If you use wireless access points, extenders or multiple wireless routers with separate SSIDs, you’ll need to ensure that you’re connected to the same network as the printer for your PC to find and install it.

If you have a new wireless printer that hasn’t been added to your home network, read the instructions that came with the printer, and check the printer manufacturer’s website to learn more and to get up-to-date software for your printer.

In most cases, all you have to do to set up a printer is to connect it to your PC. Simply plug the USB cable from your printer into an available USB port on your PC, and turn the printer on.

Select the Start button, then select Settings > Devices > Printers & scanners.
Open Printers & scanners settings

Select Add a printer or scanner. Wait for it to find nearby printers, then choose the one you want to use, and select Add device.

If your printer isn’t in the list, select The printer that I want isn’t listed, and then follow the instructions to add it manually using one of the options.
