You can save your vectorize file in PDF for file exchange with vector programs. If you print that pdf to a postscript enabled printer, it'll respect its resolution.

Now, there are other ways to vectorize in Photoshop : from the libraries panel, harness the power of Adobe capture's create from image.

Illustrator has also a revamped image tracing function.

Bonjour  I had developed a tutorial and a set of actions to Vectorize in Photoshop, I'll check if they are still available on the computer arts website.

Are you looking for actions recommendation? 

Photoshop is not a vector application and does not have the ability to vectorize an image.

You can use Image Trace in Adobe Illustrator. Results vary depending on the image itself and the settings chosen in the Image Trace panel.
