I have purchased this in March, initially worked fine. now after a month , when i print envelopes and send mail, the post man brings mail back because the ink is disappearing and no one can read the address on the envelopes.I have printed less than 300 prints, it should not do this.I suggest not buy this at all, it is no good.

TERRIBLE QUALITY... After using for about a day the ink quality dropped tremendously.. Could hardly see the print. Will not buy again!!
