Do not use the switch on a power strip to power down your printer. The printer relies on its internal circuitry to properly position the print heads. Shutting the power off at a source outside of the printer may be detrimental to the print heads or the ink cartridge. Paper makes a difference in how your document looks. Whether it is text or a graphic the quality of the paper you put into your printer is important.
Copy paper is made for copiers.
It has surface qualities appropriate for the electrostatic process copiers use to place the toner on the paper. Inkjet printers require a better grade of paper with a surface that will capture and hold the ink that is sprayed from the nozzles. Inkjet papers will also have a smoother surface and contribute less to clog up your printer. Spend a little more for inkjet paper. You will see a difference in the quality of your output.
