The invention discloses a position-based sampling triggering method for five-axis linkage curved surface ink-jet printing. The method comprises the following steps: firstly, setting a sampling period, a printing point resolution ratio and a movement speed for determining a sampling coefficient; performing curved surface continuous micro line segment position sampling linear interpolation based on an XYZAC axis; then determining the total feeding amount according to the position point movement of the nozzle and the nozzle vector; calculating the residual feed amount according to the feed amount and the interpolation interval, and sampling interpolation according to the position into equidistant interpolation; and finally, according to the curvature of the bearing surface, setting a single feed amount, calculating the feed amount of each dimension for each interpolation, converting an interpolation point into a motion component of each axis, and finally converting the motion component of each axis into a motor
