"No props" is a fairly new saying. It is a shorter way of saying "No problem/s" in a manner that expresses a willingness to help. It is not a very formal saying and is often used between casual friends.

Slang term for "accolades", "proper respect", or "just dues". Popularized in the 1980s by rappers who shortened the term "propers" which was in turn being used as an abbreviated version of "proper respect" at least by the 1960s. The increase in this term's usage during the late 1980s and early 1990s coincided with an increasing fascination with the mafia within rap circles. Both communities have traditionally placed great emphasis on the importance of earning and giving respect.

Props is short for "propers" as in, "proper respect"
On 13 Dec 2001, Joe M**** answered the question on Deja News. Here is how it is explained:

Props, short for Propers, -Don't forget that the entire word "propers" is used in the song "Respect", written by Otis Redding and most famously recorded by Aretha Franklin in 1967. At least, I think it is ("all I'm askin' in return honey is to give me my propers when I get home")-
