OT (and maybe worthy of a separate Ask HN), but how do you start a service like this that does physical printing of stuff?

Do you use a third party and just do the front end on top, or do you the whole site, printing and delivery yourselves?

For PrintSpace I used Pwinty, like @samwillis said in this thread and I couldn't agree more, Pwinty is a really easy to use printing API with a simple pricing structure.

What made them an easy choice over others was you can use them in the background like they don't even exist. Other services required users to login to their own service (or create account) before continuing which was less than ideal and created a really broken flow for a user.

Plus like @samwillis also said, they are completely white-label, putting your sticker on it if you want, making it look like it came from you.

Lastly they were very easy to communicate with, answering questions quickly and even willing to help with creating different packaging.

Some time in the future I may print my own (may be more cost effective), but for the time being this is a great choice for me.

I am using Pwinty for my site (http://www.posterhaste.com) and it is really easy to use. They do the printing and fulfilment and even stick a sticker on the packaging with your logo so that it looks like it is coming from you.

I assessed a few of the printing api services and Pwinty were the easiest and most others would ship under their own brand.

I would assume something along the lines of https://www.picplum.com/ with their API. I know Walgreens has an API for the US. There might be others, too.

Not sure what the OP is using but if you search for Pwinty or FujifilmAPI those are two printing APIs.
