The string formatting concept found in sprintf can be found in almost any language today (you know, smothering a string with %s %d %f etc. and providing a list of variables to fill their places).
Which langugage was it originally that had a library function or language construct which offered this functionality?
Please specify some kind of source reference to confirm your claim, so that we avoid pure speculation or guessing.

sprintf stands for “String print”. Instead of printing on console, it store output on char buffer which are specified in sprintf.
' Formatted string literals are a Python parser feature that converts f-strings into a series of string constants and expressions. They then get joined up to build the final string.
sprintf() in C sprintf stands for "string print". In C programming language, it is a file handling function that is used to send formatted output to the string. Instead of printing on console, sprintf() function stores the output on char buffer that is specified in sprintf.
Wikipedia has a pretty thorough history. It suggests that the C printf function had its origins in BCPL's writef function.

I would say all of them trace their roots back to BCPL. We used BCPL to do operating systems programming for the 6809 processor two decades ago and it had a writef() function which took arguments such as %i2 (equivalent to C's %2d).
C was based on a cut-down version of BCPL and inherited a similar mechanism for formatting output and I'm pretty certain all other instances picked it up from C after that.
I could be wrong, it won't be the first or last time, but I'm pretty confident that's right, given what I know about the BCPL language and its origins.
