I heard the psak about soda caps several years back. I think it was from Rabbi Abadi (who has a large following, but im sure that there are people here that don’t “hold” of him, even though he was appointed by Rav Aharon to be the posek of Lakewood. Anyway you don’t necisserily have to “hold of him” for it to be a limud zechus). I am going to try to ask someone who knows his pesakim better to make sure.
You bring up a good point. How is it different than ink which is made up of tiny molecules as well?
I can think of two sevaros off hand.
1. When you magnify ink, even a billion times, you will see that all the molecules are attached and connected, with no spaces in between. But if you magnify print, you will probably find small gaps and spaces between the dots.
2. It is possible that the end result is the same, but the manner of “ksivah” is different. The printer doesn’t necesserily create the dots in order. For example, for the word “the”. First the printer may put a dot on the bottom of the “e”. Then a dot on the top of the “h”. Then another dot on the bottom of the “t”, etc.
Since it is being written in this “jumbled” manner, where the dots of the letters are being formed out of order, this is not considered ksivah.
But to get the right sevara, it would probably be best to discuss it with the Rav who gave the psak in the first place.
Someone mentioned something about writing on a computer screen, that it is ksav gamur that will later be erased.
That is a very interesting sevara, which can probably have other applications. It gets into the reason behind the din of ksav sheino miskayaim.
But even so, i believe that an image on a computer screen is refreshed hundreds of times a minute, so that may anyway make it ksav sheino miskayaim. Is the Rav who issued that psak aware of this?
(this is definitly the case with the older “fat” screens, and im pretty sure that it is true with the new “thin” screens as well.)
