Ink-jet printing device used for continuously printing media

The invention discloses an ink-jet printing device used for continuously printing media. The ink-jet printing device used for the continuously printing media comprises a framework, an ink-jet unit with a printing head, a paper-moving channel and a paper-moving mechanism, wherein the ink-jet unit comprises an ink box accommodated with quick-drying ink to ensure that the quick-drying ink which is jetted by the printing head and attached to the continuously printing media is solidified and dried up before arriving at the paper-moving mechanism, and therefore the problem that a friction wheel scratches ink marks which are not dried and accordingly images are distorted is solved. Further more, a horizontal paper-moving channel for ensuring that the continuously printing media horizontally move is adopted by the device, wherein the horizontal paper-moving channel is a straight-line-shaped paper-moving channel and discards an L-shaped or a C-shaped paper-moving channel mode on a traditional ink-jet printer, reduces
