Print quality is different with plain paper and matte label paper which is strange and confusing

[twisted118]

So i had to purchase a new printer that enables boarderless printing so i purchased the officejet pro9015. now my issue is i print the same document on plain paper setting and plain a4 paper in the tray and it comes out really nice colours etc. When i insert the matte a4 label paper it doesnt allow me to select plain paper so matte paper is the next best option but the quality is rubbish colours are washed out i will add some links to the quality difference for you to see. no idea why it prints different on plain and different on label paper as there both matte.

Ink colors will appear different on different media as the amount of ink absorbed by the substrate will vary. If you are not getting all print options, check to make sure that you have the correct driver installed.

i think it is just the paper in general as 2 different types of matte label paper its still the same result
