Then why not reply to that thread, or at least keep the same subject...?

Before going to the complexity of colour profiles, a quick question - 
does this only happen with GIMP, or other applications (e.g. LibreOffice 
/ Word) as well?

From what I recall of your previous message, the printer hadn't been 
used for those several months. If all applications are affected, it 
sounds like you may have dried magenta (red) ink clogging the printer. 
Although you replaced the cartridges, ink can still dry in the print 
heads, and maybe even between the cartridge and heads.

Your printer probably has a feature to print a test page, usually 
accessed from the printer properties, which will print some patterns in 
various colours to check for blockages. One other thing I often do when 
having problems with colours is to create a page of text in LibreOffice 
consisting of the following in a large bold font:
  RED
  YELLOW
  GREEN
  CYAN
  BLUE
  MAGENTA
  BLACK
Each word formatted in the corresponding colour. Print that and see how 
it comes out. I suspect the magenta will come out faint if at all, and 
the red and blue will be off-colour (the red appearing more towards 
yellow and the green more towards blue).

Alongside the test page feature, your printer probably also has a 
head-cleaning function. It might need to be run several times to clear a 
severe the blockage.
