Example code

printerSlowPrint("Its too cold here...z.z..z.z.zz\n");

Instead of printing characters one-by-one (as intended)
It will output the entire line on the terminal all at once after some delay

This behaviour was not found with same codes under Windows test builds
Potentially due to some buffered output behavior on Linux by default

The issue can be mitigated by Disabling buffering on stdout

setbuf(stdout,NULL);
printerSlowPrint("Its too cold here...z.z..z.z.zz\n");

More information here :
Why does printf not flush after the call unless a newline is in the format string?
