You need a PSP with a custom firmware, if you don't have one installed, I recommend to follow this tutorial.
On your PSP, when you are on the XMB, press "Select" button to open the VSH menu, then move on "USB DEVICE" and choose "Flash 0" thanks to right/left on your D-Pad and finally move on "EXIT" and press "X" button to close the VSH menu. Now, connect your PSP to your PC and you will have access to the fonts, simply copy them in the corresponding folder in your PPSSPP folder
Afterwards, don't forget to put back "USB DEVICE" on "Memory Stick" in your VSH menu, otherwise you won't have access to your Memory Stick anymore
WARNING : Don't delete any file in your Flash 0 folder or your PSP will have major issues
