What are the recommendations to print it then? That's half the reasons why I would buy it.

Local print shop that deals with large/poster prints. They'll usually be happy with a high enough resolution PNG, and can advise you on what's the best way to print in the physical size you want - what material to print onto, what printing approach to use, what finish to do, how to frame it, etc.
I work at a print shop and all our printer drivers require PDFs, so use those if you want something printed please. We can convert as need be, but PDF is always preferred.
Every worthwhile print shop has staff that can do the conversion to meet the needs of their specific printers.
But they will upcharge for it.
Not in my country. That's their job. It's part of printing.
If you came with anything prepared at all, they're happy.
And getting vector files out of OSM data shouldnt be too hard either.
That is kind of the thing.
Getting the image is trivial. The real effort is getting it printed and getting a frame for it. And the cost of that tends to be pretty close to just buying a pre-print. And stuff like this tends to be sold in museums or other local/government buildings and genuinely goes towards some great community programs.
That said, there are some great sites for this. There are cheaper websites, but Stackhouse is generally a great choice for printing. Especially if ou want a canvas print. Frames you are almost always best off going to a pawn shop or local art supply store, but even amazon is not a bad choice for that.
Combine that with realizing just how many museums upload high quality scans of genuine works of art and...
Amazon is always a bad choice for anything.
There's a fork with emphasis on public transport: https://git.olaren.dev/Olaren/maptoposter
Sadly this fork is missing the feature to set custom sizes :(
I could not get it running on my local Linux machine. Looks like some error involving one of the packages. A shame. Added an issue to the board. Ill take a look in a bit after they fix the bugs.
It would make a good website to be honest. Most people will probably only want a one off of their home city.
I used it a couple of weeks ago, must be a new bug then
Its a combo of my os, pip, and thier requirements file.
Did you try it with venv? That might reduce the chance of interference with your system
A python script that can print and frame a poster? Impressive.
The Singapore one is really striking!
Does it make vectors?
PNGs by default, I'm not sure if vectors are possible yet but it seems like it would be easy to implement
Seems like there was a merged pull request to add SVG/PDF support: https://github.com/originalankur/maptoposter/pull/57
