In the mid 80's DC comics had acquired licenses to several TSR settings and released comics based on those properties. For the Dragonlance comics, the stories were told in an anthology format, with about 3-4 issues completing one tale. The stories were set in various times and with various casts.
Later in the run, the comic settled on a set of characters and kept the stories at around the same time.
At the very end of the comic run, it once again returned to an anthology format spread across different eras (as well as different writers and art teams). After 34 issues, the comic ended publication.
It is interesting to point out that none of the comics are adaptations of existing novels or short stories, though major characters like Tanis Half-Elven and Raistlin do appear in several of the stories.
