Please not the CMYK again... That's wrong.
Unless you have a manufacture printing millions of carton every day for your favorite hot/cold drink, toilet paper or cereals' boxes and need colors separations (to save ink for example) or being a logo designer for a printing company, I think that I can safely tell that this pseudo "argument" is quite irrelevant nowadays for 99% of the planet.
There are a lot of math, science and theories behind RGB to CMYK, icc device profile to printer color space... but there is too much to speak about this for this thread.
As you're saying:
It seems you never print with GIMP... Try, you will be surprised as it does a good job.
Tell me, when you print a webpage, do you convert it to CMYK? No! but your webpage is well printed although it has the color profile of your monitor -> RGB/sRGB...
When you print from your favorite office suite like LibreOffice, do you convert your document to CMYK? No! but your favorite office suite does a great job at printing...
For most people who just wants color on paper, it doesn't matter since the built-in color profiles in printers do a nice job converting RGB to CMYK.
Do you know that CMYK start with white (paper), thus the Key (K), -> no paper are pure white, and depending the brand (even in the same brand) the whiteness will be different, for example they are slightly yellowish/blueish/grayish, and even the level of gray or yellowish is different...
If the "whiteness" of the paper do not match the Key, you're not going to get what you've expected...
Go to a printing shop and ask the workers/owners what's the profile people come in with their image to print in their shop, they will tell you that 99% come with RGB/sRGB/ARGB, and (almost) never with CMYK.
I certainly have one of the cheapest printer in the world using CMYK inks (Epson L220, bought around 120 USD 5 years ago), I print, have printed and will continue to print from GIMP on that printer until it dies.
I have printed pictures for passport, pictures for IDs, printed my photos. I have printed drawing like a ludo game, snake and ladder and so that I did made with GIMP and printed from GIMP (for my kids), color are absolutely normal, no noticeable deviation...
Oh, and all that without "converting" to CMYK, how about that
You do not need to convert to CMYK, because your CMM/S (Color Management Module/System) either from the computer or the printer itself will do it.
In the end, it's how you've set up your printer.
Last but not least, GIMP has a softproofing CMYK colours (I never used it), GIMP can generate CMYK separations (I never used it), CMYK TIFF image, in > Change color FG-BG you have a CMYK tab (I never used it)...
