How do I find already printed photos

Hello,

I have an image that I will make an adjustment to and print a sample for review. I review the print and make adjustments in Lightroom and print a revised version.  I may do this 5 to 6 times with a differnt adjustment for each of the same  image before I decide which printed image of the 6 or 7 I like.  My problem is I do not how to go back to image 3, for example, if I like  image 3 the best.   I currently am doing this by saving each image to a desktop folder via Save as JPEG then importing the file and either printing it or perhaps making a slight adjustment then printing.  This is very cumbersome plus sometimes I am working with a RAW photo and be saving it as a JPEG has limitations as to further editing I may want to do.  Any suggestions as to have to be able to go back and find  printed images would be appreciated.

Thanks,

Steve
