Plugin / Google Cloud Print Library

Description

This plugin is mainly for programmers to use. It contains an options page to set up a connection to a Google account, and allows you to choose a Google Cloud Print printer from your account and to test printing to it.

The main use of this plugin is for developers of other plugins to deploy, and integrate with their plugins. For example, it has been integrated into this plugin that can send orders (invoices, delivery and packing notes) from a WooCommerce web shop automatically to Google Cloud Print.

To set up WordPress to have access to Google Cloud Print, you will need to follow this reasonably-simple tutorial: https://www.simbahosting.co.uk/s3/support/configuring-google-drive-api-access-for-cloud-print/

How can a developer use it?

Here’s some example code:

// Ensure that we can get a Google Cloud Print Library object

if (class_exists('GoogleCloudPrintLibrary_GCPL_v2')) {

    // The first parameter to print_document() is the printer ID. Use false to send to the default. You can use the get_printers() method to get a list of those available.

    $gcpl = new GoogleCloudPrintLibrary_GCPL_v2();

    $printed = $gcpl->print_document(false, get_bloginfo('name').' - test print', '<b>My HTML to print</b>');

    // Parse the results
    if (!isset($printed->success)) {
        trigger_error('Unknown response received from GoogleCloudPrintLibrary_GCPL->print_document()', E_USER_NOTICE);
    } elseif ($printed->success !== true) {
        trigger_error('GoogleCloudPrintLibrary_GCPL->print_document(): printing failed: '.$printed->message, E_USER_NOTICE);
    }

}
