Finding all my owned minifigs
If you have added your sets to Brickset, under "My Sets; Minifigs; View Your Minifigs" you will find all your minifigs pictured &amp; listed by name (default). This will give you their name, ID number, and which set or sets they are from. You also have several more options to sort them by. Clicking on a picture magnify's the figure for greater detail. All of this can be printed, but given the number of minifigures you are dealing with, printing them out is going to take a lot of paper and ink and may be impractical.  

   

If any additional information is needed, then looking up the provided figure number on Bricklink will give you the option to look at its individual components in greater detail.
  

Brickowl can provide you with a more compact, detailed break-down of a minifigures parts, but unfortunately doesn't use the same ID numbers as Brickset and Bricklink. These compact inventories would make it more practical to compile several figs on a single page. Perhaps Brickset may consider such a format if you were to inquire? It would be a very useful tool.
