It is very easy to print things that are true but still have a bias. For example, printing things that are true but good about one political party, while printing things that are true but bad about another, is a bias. Almost every news medium has some kind of bias this way, and I think it affects their impact more than if they simply tell lies or not.
(Counter to the current worry, it seems to me that outright lies in mainstream publications are actually somewhat rare. When they happen they are generally corrected. Though there is a recent trend of rushing to publication to appease an overly emotive audience, getting things wrong, and then having to correct days later, after everyone's already been influenced. NYT especially.)
This used to be somewhat addressed in the US television segment by taking it even a step further, and requiring news shows to not only be truthful, but represent both sides of controversial issues. It was called the Fairness Doctrine [1], but it was revoked in 1985.
