Hi,
which type of printer?
How old is your printer or print head?
how much the print environment temperature?
ink temp? ink expire? alternative or oem ink?
head high is low or high?
carriage speed normal or high speed?
on test print everything all right?

for giggles, look under your carriage, it looks like you have trash stuck under there. Additionally, once a printhead starts to go, you can get some odd results. This could also be the case, but the picture isn't big enough to be able to look at the edge to see if it's just one color or all colors.

Clean the encoder strip, clean the bottom of the carriage are the places I would start.
