printing wrong colours

hi everyone, can you help?

I dont know what ive done but my printing has messed up, reds are pinkish and blacks are more grey, using corel but if i scan a pic and print it direct it comes out fine???

What have i done?

 

I did change the inks recently then had a click through the printing options somewhere within corel but cant remember where, what i clicked on and clicking defaults dont make a spot of difference??
