A Canon BJCSP2000 printer was included in my computer package. I naively thought I could also install my HP Laserjet 5L & just take out the HP plug & put in the colour printer one when I needed it. It was not to be -- the HP printed at about 1 page per minute instead of 6. I have uninstalled the Canon as I use the HP a lot. Do I need to get another port for the colour printer or is there another solution?
