Simply, takes your tiles and reduce the image quality a bit to recude the printing costs, and then take those lower cost and slightly lower quality images and print them.
Group them into sets and glue the tops of the and sell the pad at stores for people to buy "tiles" rather than having to print them out themselves to replace the current game board stock tiles, so they are cheaper to buy, cheaper to replace, and can be cut to size for what you need without worrying about destroying them as the "basic set" of tiles will NEVER go out of print as long as the product lives.
The dungeon floor plans is close, but still stiffer stock like most module covers and would cost a bit more. The dungeon floor is on the right track, but you would need more than that and have things like your own tiles thrown in so it isn't like just buying a "blank" mat from Chessex or where ever.
All in paper, and all types of tiles. This way you can cut out lengths of corridor that you need rather than being stuck with 10 or 40 feet lengths, but can cut your own size and have much more custimization of dungeon and overland design as if you had enough sets of
Dwarven Forge - Miniature Terrain maker of MasterMaze for Warhammer miniatures, Star Wars miniatures, D&D miniatures , Reaper miniatures, and Lord of the Rings Scenery to make exactly what you want...but cheaper and out of paper so it could be disposable of even reusable.
Get tired of using a room, turn it over and write on the back of it.
Then you find a map in a published adventure and need to make it you can use your paper tiles to make it so that it may be the same floorplan as the one in the book, but has your preferred tiles to use rather than the default ones.
Say you didn't want Tudor style buildings, but wanted stone, then you just grab the stone tavern that is 4x8 quares and plop it down. Choose which table tile you want and plop them down in your own pattern to design the room interior. Even if brave enough have a tile for the bar itself so you can have empty buildings and turn whichever you want into a bar.
Either leave them lose for those that need to move of tape them down or stick them with a glue stick or other adhesive.
Look at the WotC dungeon builder and see how you can overlap tiles and such to create a design, and think it you had paper tiles that you could do that exact thing with so that certain parts overlap, but you can cut out those parts.
The idea came form looking over the old Geomorphs and how you photocopy them out, but these "paper tiles" are sold and don't require printing yourself, but PDFs available for people that want to print them themselves.
Like I say your tiles would be great as a start to have printed and sell, IF people didn't mind doing the work to have the customization of creating their own rooms and designs, and is seems many do, and the printed ones may be cheaper than ones you print yourself.
Hope that answers your questions.
