Over the years there have been quite a few paper safes that would dispense one sheet to you when you opened the door. I use one all the time for 8x10. This would be for cut paper. The other options are roll paper easels which take a large roll on one side and a take up spool on the other, with the easel area in the middle under an orange colored door, which you compose on, then lift up to expose the paper. Push a button and the paper advances. Quite popular in small to mid-size color labs at one time for package printing with cluster lenses on the enlarger. Nord use to make these, if you want a brand name.
