When printed colour not right and vertical lines appear

SOURCE: Colour printing

If the test patterns are not matching what your printer tells you is normal and your photos are banded horizontally, you may have clogged nozzles and printhead. Do a maintenace clean under your printers direction, and see if it now prints ok. Also, you may be low or out of one particular colour, but still have enough of the others and the printer will try to compensate by using available colours, hence colour banding and distortion. A manual clean with cotton buds and cleansing solution is recommended if the first clean does not help.

Attach an external monitor (you may need to buy an adapter to try this) and turn on Display Mirroring in the Display preferences.
If the same symptom shows on the external monitor, then you've got a video card problem. If not, I'd say you're screen has some kind of damage of failure.
Sorry, but either one is likely going to require a trip to the Apple Hospital.
At least with the display problem, you could use the external monitor until repaired.
