I think the waste of effort and devastation will be terrible. The closing down of stuff for “security reasons” rather than doing it properly and securely is a blight on our industry. Countless businesses and facilities will be lost. But I have no reason for optimism that it will be otherwise. Hence I make it part of my task to make sure people understand FLASH WILL GO AWAY rather than skate over the message. It’s not too late for some to save themselves.

> I think the waste of effort and devastation

yes indeed, that's why I'm optimistic, because I never saw users, btw people to just accept a disaster, rather something better will be built on top of it, and I''m very confident that today very good developers with good ideas all around the world can change/adapt, give oppotunities to many to solve unnecessary problems.

I think you’ll find Microsoft believe they CAN block Flash in IE, and you know, I believe them. “

By the end of 2020, we will remove the ability to run Adobe Flash in Microsoft Edge and Internet Explorer across all supported versions of Microsoft Windows. Users will no longer have any ability to enable or run Flash.”

Whether the download server is turned off is an interesting question. But would you keep running an old version if security problems are no longer fixed? Every hacker in the world will see you and your customers as an easy target.

But it is almost unimportant (for the developer making choices) whether the server is turned off because all major browsers will block Flash before the end. Most major browsers now auto update so users will simply not be able to choose to use Flash.

What you said is impossible. For IE, FLASH is only a ActiveX control, IE can not cancel the support for ActiveX control, so as long as IE can be used. We can force customers to use only IE browsers.

Miracles can happen. When they do I plan to seize them. But a plan to rely on them might prove hard to justify to stockholders.

Flash will go away by 2020. Some browser makers have an earlier target. Adobe have no say in this now, the browser makers are blocking it one by one. Already they are making it difficult. Still think there is a fortune to be made?

You're welcome. Silverlight ceased development in 2013. I believe that to have the smallest chance of this all happening again, HTML5 is the way to go, even if it limits inventiveness.

HTML5 never been a substitute of Flash, it's HTML5 + JAVASCRIPT

You fools, if you use FLASH to develop a set of ERP, you will earn more than SAP.

Printing support in Chrome (via PPAPI) is very limited. The PPAPI specification is frozen, and Google's agenda is to deprecate Flash support in the browser. You're welcome to file a bug, but it's a browser limitation, and unlikely to get fixed.

My recommendation, given that it's 2019 and we're rapidly approaching the end of the Flash lifecycle, would be to render your output in HTML and JavaScript and print from there. You could use ExternalInterface to invoke that activity from Flash, and JavaScript libraries targeting HTML5 Canvas for rendering complex graphics, barcodes, etc, or maybe assemble a ByteArray of what you want to print and push that over to JavaScript for rendering as an image.
