A method of controlling a micro injecting device performs spitting action which sprays ink from nozzles to maintain the clean state of the nozzles of the micro injecting device. The method includes the steps of: storing respective code values corresponding to the numbers of the nozzles that have sprayed ink among all the nozzles, in a storage section, when printing is initiated; detecting a spitting action performance time while checking the number of printed pages; checking the code values of nozzles among all the nozzles which have sprayed ink over a predetermined frequency during printing by using respective code values stored in the storage section, if it is a spitting action performance time as a result of detection; searching for computed remaining code values by computing the code values of the nozzles that have sprayed ink from reference code values which correspond to all nozzles pre-stored in the storage section; and performing spitting by spraying ink from nozzles which are determined to correspond to the remaining code values as a result of searching. Therefore, before performing spitting, by checking respective nozzles used during actual printing and comparing them to all the nozzles of the micro injecting device, and allowing spitting for only the nozzles unused during printing among all the nozzles of the micro injecting device, unnecessary consumption of ink is prevented.
