What do I need to bring to immigration regarding my TM30 report after checking into a hotel in Bangkok?

I go to immigration at CW Bangkok tomorrow morning. Thanks for the great answers yesterday. I'm trying to avoid the tm30 fine of 600 b or whatever.

Regarding the receipt for the tm30 ... I just checked into my hotel and they showed me the tm30 login screen that they will use to report me as staying in their hotel in Bangkok.

But when I asked whether they can print something out from the tm30 report for me to take to tomorrow, they were pretty much Clueless. I'm thinking if they can't print something out tonight showing they tm30 reported me then at least I can arrange to take a screen grab while they are reporting me on the tm30 online. Doesn't sound right though.

Or is the thing called a tm30 receipt something that immigration will have tomorrow that they can print out after the hotel reported me. ?

Sorry I spent a good hour looking at the dedicated tm30 link and did a search but cannot find how I actually get something printed out to take to to immigration that shows the hotel reported me.

The immigration visit is to transfer my typo O extension from the old passport to the new passport but I would still like to have that first tm30 because today I entered the country after many months out of Thailand.
