The paper introduces the design of time print and power-down monitor unit based on Ultrasonic Flow Meter (FLYS1213).

Accurate orientation printing has been widely applied in every trade of applied software.

Enhanced Locked Print Application for Ricoh MFP;

Scanning electron microscope (SEM) was used to characterize the surface structure of the coating layer, and the printing color density was applied to value the printing quality of the coated papers in order to carefully investigate the effects of fumed silica, nanometer silicon oxide and gelled silica on coating structure and printing properties of ink jet papers.

The experimental results indicate that the printing property of the sample sheet after sizing was near to that of the paper coated by silicon, thus an improved ink jet printing paper with low price .
