I take it you're dissatisfied with your results. It would be helpful to know a bit more.
Different to what paper?

Thee will have an effect on results.
I take it you are using the correct profiles for your paper and ink combination.
If your printer has grey inks in addition to black you'll get better results.
Many papers are suitable, and there's such a wide range of finishes and textures, so much is personal choice..
Many manufacturers have profiles to download for their papers and different printers.

It is very difficult to give advice when you are not telling us a lot... Matt paper has a low D-max, meaning the depth of black will not be good. What are you trying to achieve?
My own favourite for monochrome is a baryta coated paper which results in a look very similar to traditional darkroom prints.

I use papers from Paper Spectrum , usually the Premium Lustre for both colour and mono using a Canon Pixma Pro 100. They will do a free ICC profile for you and I get great results from mine. Their papers are excellent and cheaper than the big brands like Olmec etc.
