I'm using Froala Editor in my Angular project, and I'm relatively new to it.
In my setup, I have a single Froala editor instance shared across multiple pages. When I switch between pages, I clear the content of the previous page and reinitialize the editor with the new content.
I want to add a custom "Print" button to the Froala toolbar that prints the current content of the editor. I followed examples like this one: Froala Print Button Example, and it works fine in that context.
However, in my Angular project, when I click the print button, the print dialog opens but the content area is blank — it doesn’t show the editor content.
I suspect it might be related to how I'm reinitializing the editor when switching pages, but I'm not sure. Has anyone faced this issue or can suggest how to properly print the content from a reinitialized Froala editor?
Here is my code:
private editorOptions() {
const newUniqueId = this.generateUniqueId();
const loggedInUserId = this.userInfo?.userId;
this.options = {
key: Froala_Constants.LICENSE_KEY,
attribution: false,
fontFamilyDefaultSelection: 'var(--font-NeueHaasDisplayLight)',

'Neue Haas Display Light': 'var(--font-NeueHaasDisplayLight)',

imageUpload: true,
imageDefaultAlign: 'left',
imageDefaultDisplay: 'inline-block',
// Set max image size to 5MB.
imageMaxSize: 5 * 1024 * 1024,
// Allow to upload PNG and JPG.
imageAllowedTypes: ['jpeg', 'jpg', 'png'],
imageUploadParam: 'image_param',
// Set the image upload URL.
imageUploadURL: urlPathConstants.imageUploadUrl,
// Set request type.
imageUploadMethod: 'POST',
