Use the Section38 app in Google Play. Hard to find, but extremely easy to use; much easier than the online site. (I use the word "possessor" where it translates to "residents.") It sends your report to the same online site where you can then print. Easy, peasy. Registering initially online is also easy.
For some reason, all my Immigration locations (Jomtien, Chaengwattana) keep handing me back my copied (yes, copied) TM30's as if they are the originals. (but nope, just copies) ????
I just scan my passports (yes, every page separately) and docs in color and print in black-and-white just the specific pages when needed to take. ????
