Great question, It seems you are using a printer that is used for printing CD/DVD labels and Photos. Which should not be used for general office work, due to the price of the ink.
Most printers will have similar troubleshooting / calibration steps that it makes you go through at setup, more so with a photo printer as it trying to keep its accuracy over time.
You should really have one printer dedicated to printing photo quality images and then another for general office work. In that case you should take a look at getting a laser printer that prints only B&W, Brother monochrome laser printers I have always had good luck with and will not require as much troubleshooting / calibration.
