The present invention provides a conductive paste for an outer electrode of an electronic part comprising glass frit, a vehicle and conductive particles, wherein the glass frit comprises. The method comprises providing a transmit queue having a head and a tail and providing a retransmit queue having a head and a tail. Then, a voltage measured at a voltage measurement point Q is compared with a threshold value to detect whether or not the leakage exists. The first printer driver andor the second printer driver rewrites the print-attribute settings thereon without fail on the basis of the job-ticket data, and transmits drawing data generated on the basis of the rewritten print-attribute settings to a printer. A salver is located below the axle, and is slidably connected to the support portion.
