A topic from AEG's L5R CCG Rules forum, copied for Oracle of the Void from a copy of the forum saved in October 2015, so pages it didn't save are missing. Players' names are left out; the rules officials are named. Rulings are as they stood on these dates; later rulings, the rulebooks and the Rules Archive may differ.

This is so obvious that no one bothered to even explain it
What are requirements for a card to qualify as "MOST RECENT PRINTING" ?
For example - which copy of "Know No Fear" is technically considered MVP : - from Emperor Edition Gempuku (Unicorn) starter - because it is last to be printed as for today, although it is undistinguishable from first copy from Second City (except maybe flavor) ? - from Alternate Art packages - because it is last to be printed AND with different identification than first copy ? - the orginal one from Second City - because neither Alternate Art or EEG reprint changed anything in rules regarding the card ?
Thank you for stating the obvious
EDIT (2013-01-16) : Thank you for your post, unfortunately you did not answer the question, and example with Agasha Ueda is misleading due his history of prints. Sending PM to clarify, thanks!

Most Recent Printings only really matter when a card's stats or rules text have been altered with a new printing of a card by name. Changes to art and flavor text have no bearing on what MRP constitutes.
In your example, while the most recently printed version of the card is in the EE:Gempukku set, since none of the stats nor rules text have been altered by this new printing, there is no MRP with respect to deck legality and playing the card within a game.
Agasha Ueda is a prime example of how MRP works. If you look at the card entry in the Oracle of the Void, you can toggle between the CE and CE:15 printings to see the gold cost increase from 4 to 5. Also in the Oracle, the stats and rules text written on the right hand side of the card images is always the MRP.
