Google Maps API V3 Print Google Maps with Markers using JavaScript

In this article I will explain with an example, how to print Google Maps with Markers using JavaScript and Google Maps API V3.

Google Maps API V3 provides Static Maps API to take Screenshot (Snapshot) Google Maps to Image. Once the Image Screenshot (Snapshot) is ready, it will be sent for printing using JavaScript.

Print Google Maps with Markers using JavaScript

The following code snippet consists of an array of Markers of different Geographic Address locations. Each marker in the array contains title, latitude, longitude and description of the location.

Inside the JavaScript window.onload event handler, the LoadMap function is executed.

A loop is executed over the array of markers and one by one each marker is populated on the Google Map.

When the Print button is clicked, the Google Map properties such as Center, Size, Zoom and MapType are fetched from the Google Maps mapOptions object and are appended to the Google Maps API V3 Static Maps API URL.

Then a loop is executed over the Markers and their Geographic address details i.e. Latitude and Longitude values are appended to the Google Maps API V3 Static Maps API URL and the URL is set as source to an HTML IMG element which displays the Image of the Google Map.

Now the contents of the HTML DIV which contains the Google Map Image are sent to the PrintDiv function, which prints the Google Map along with Markers.

Note: For more explanation on printing HTML DIV contents, please refer my article Print DIV content without opening new popup window using JavaScript.
