IMPOSSIBLE to have 300 ppp on jpeg when export / save as / save as copy

[Nirina Andria]

I need my photo in 300 ppp for print and i tried everything to have it when i export it on Photoshop AND lightroom classic but always end up with the poor 96ppp.

I tried everything :

- Save as

- Export

- Save as copy
- changing the " Preferences > File Handling > File Saving Options" Enable legacy "save as"

nothing change still 96ppp.
lightroom export make the same thing.

any suggestions ?

Save As/Save a Copy JPEG will retain the 300ppi resolution metadata. Export As will not, Save for Web depends on the metadata inclusion option selected.

[Stephen Marsh]

The following scripts will force the resolution metadata of a previously saved JPEG file to 300 PPI without opening/resaving the JPEG image data.
