How to listen print action in remote renderer

[nikhilranosys]

I have implemented remote renderer with updated structure and want to implement my own print action suggested on this link: https://github.com/OpenCerts/opencerts-website/issues/444#issuecomment-558474653

But I am not sure how to listen parent's print action in iframe.

How do you connect through the frame:

• Do you use like the example FramedDocumentRenderer ?(https://github.com/OpenCerts/demo-opencerts-renderer/blob/master/src/index.tsx) => in that case there is nothing to do
• Do you implement yourself the connection to the iframe ? then you need to provide a print method (same as renderDocument function)

If you are unsure, feel free to provide a link to your code so that I can help you through it

[nikhilranosys]

Here is my code repo link: https://github.com/nikhilranosys/demo-opencerts-renderer/tree/smu-templates-new

You are using FramedDocumentRenderer, it should work, isnt it the case ?

Could you upgrade @govtechsg/decentralized-renderer-react-components to latest version ? 1.2.1

[nikhilranosys]

Yes, print is working but pages are faded because of the default watermark. I want to add my own watermark thats why want to listen print action.

[Nebulis]

ok Upgrade to 1.2.1 it should fix that problem (that was the fix reason)

[nikhilranosys]

I have already upgraded to 1.2.1 but still getting same issue. It is showing gray layer in print version though I have different watermark set on my page.

[Nebulis]

How do you print?

• using the print button ?
• using a shortcut (ctrl+p / cmd+p) ?
• using the menu ?

[nikhilranosys]

Using the print button.

[Nebulis]

It should work, I will try with your repository but in the meantime make sure your local version of opencerts-website is up to date as well

[Nebulis]

Feel free to remove whatever is related to govtech (for instance govtech examples in src/templates/govtechDemoCert)

[Nebulis]

I just tried with latest opencerts-website and your branch, and didn't face the issue.

However I couldn't see your Watermark as well. I had to do the following change:

export const PrintWatermark: FunctionComponent = () => (
  <div
    css={css`
      width: 0;
      height: 0;
      opacity: 0;
      display: none;
      position: absolute;
      background-color: blue;
      background-repeat: repeat;
      z-index:1000;

      @media print {
        width: 100%;
        height: 100%;
        opacity: 0.6;
        display: block;
      }
    `}
    className="print-only"
  />
);

(adding z-index L14)

This is what I get locally Printed from my local opencerts (latest version) using your branch and the line I added

Thanks for the update. Now it is working perfactly fine when I run with npm run start.

But when I try to export using npm run start:static I am getting below error:

I'm not sure what's going on, There are some issues that could be related on next repo (https://github.com/zeit/next.js/issues?utf8=%E2%9C%93&q=Module+did+not+self-register)

I cant reproduce on my machine (linux)

What are you trying to achieve ? (why do you build opencerts yourself)
