Well, if the print was the same as what you saw on your monitor, it seems you don't really have a printer problem. Can I suggest you try something easy first? Buy some good quality glossy or pearl RC paper and print on that. It's likely to be much better suited to the sort of intense colour, high contrast style motorcycles are usually shot in. Then when you've got something that works (and is relatively cheap), go try the trendy barytas, then finally move onto the mattes.
