Your prints being off has nothing to do with the color space and everything to do with proper color managed calibration. You need:


1). An external colorimeter (like Color Munkey or Spyder etc) to profile your monitor, which is always step 1. Without this, proper color management is impossible.


2). Then, you need to install profiles of your devices such as printers, but also of external devices at service points or labs (profiles of their machines).


3). Then you need to make everything connect on the software side of things (I only use Lightroom and Photoshop so cant tell you if or how DPP handles color managed workflow) and THEN you have control over color consistency between what you see and what you reproduce.





Mind you, most cheaper monitors can only reproduce sRGB anyway. More expensive monitors can show the (much wider) Adobe RGB gamut (which handles shades of various colors better but *can* cause duller looking pics unless postprocessed a bit. Also: converting between the formats is useless because converting between sRGB and Adobe RGB wont give you extra colors. And if you shoot RAW, you may want to consider working in an even wider color gamut called ProPhotoRGB, which is the native color space of Camera RAW. But having a properly calibrated and high-end monitor that can actually display all these colors is a good starting point.





So is reading color management for dummies by the way. Not meant in an offensive way. But I see SO many questions about this I am beginning to wonder if there shouldn't be a FAQ in some topic but I am too lazy to write it. It's not *that* complicated but is is complicated enough to type it all myself.
