As far as I can tell, no it is not compatable with your camera, sorry. I use it in the Polaroid Pogo printer. I think it is a heat sensitive type of 'paper' for 'special', inkless printers.
I think your camera needs a 'self developing' photographic paper.
Hope this helps you a little?
Hi, I've just looked up the lg ps2203 on the web and the internal packaging of the paper looks to be identical with what I bought for the Polaroid, Even the diagram appears to be the same.
Also, the measurements are exactly the same. So, if it was me, I would take a chance on it. Maybe just buy a small amount first and if it works fine.
All the Best
