A method for controlling pauses in printing, including: transmitting imaging data to an imaging unit, and transmitting a printing signal whilst transmitting said imaging data of each page, wherein said imaging data are printed when said imaging unit receives said printing signal; wherein printing said imaging data is stopped when said imaging unit cannot receive said printing signal, characterized in that the method comprises generating a command of pausing printing upon receipt of a cause of pausing; stopping transmitting said printing signal to said imaging unit according to said command of pausing printing (S30, S104), wherein, said imaging data include double-sided imaging data, and said method for controlling pauses in printing further includes: counting the printing signals for the imaging data on a front side and the printing signals for the imaging data on a back side, respectively; wherein, stopping transmitting said printing signal to said imaging unit includes: stopping transmitting said printing signal for the imaging data on the front side immediately upon receipt of said command of pausing printing; continuing transmitting said printing signal for the imaging data on the back side; stopping transmitting said printing signal for the imaging data on the back side immediately when a count of said printing signals for the imaging data on the back side is equal to that of said printing signals for the imaging data on the front side (S106, 5107). transmitting imaging data to an imaging unit, and transmitting a printing signal whilst transmitting said imaging data of each page, wherein said imaging data are printed when said imaging unit receives said printing signal; wherein printing said imaging data is stopped when said imaging unit cannot receive said printing signal, characterized in that the method comprises generating a command of pausing printing upon receipt of a cause of pausing; stopping transmitting said printing signal to said imaging unit according to said command of pausing printing (S30, S104), wherein, said imaging data include double-sided imaging data, and said method for controlling pauses in printing further includes: counting the printing signals for the imaging data on a front side and the printing signals for the imaging data on a back side, respectively; wherein, stopping transmitting said printing signal to said imaging unit includes: stopping transmitting said printing signal for the imaging data on the front side immediately upon receipt of said command of pausing printing; continuing transmitting said printing signal for the imaging data on the back side; stopping transmitting said printing signal for the imaging data on the back side immediately when a count of said printing signals for the imaging data on the back side is equal to that of said printing signals for the imaging data on the front side (S106, 5107). counting the printing signals for the imaging data on a front side and the printing signals for the imaging data on a back side, respectively; wherein, stopping transmitting said printing signal to said imaging unit includes: stopping transmitting said printing signal for the imaging data on the front side immediately upon receipt of said command of pausing printing; continuing transmitting said printing signal for the imaging data on the back side; stopping transmitting said printing signal for the imaging data on the back side immediately when a count of said printing signals for the imaging data on the back side is equal to that of said printing signals for the imaging data on the front side (S106, 5107). stopping transmitting said printing signal for the imaging data on the front side immediately upon receipt of said command of pausing printing; continuing transmitting said printing signal for the imaging data on the back side; stopping transmitting said printing signal for the imaging data on the back side immediately when a count of said printing signals for the imaging data on the back side is equal to that of said printing signals for the imaging data on the front side (S106, 5107).
