In the present study, the air pollution of hp 1200 and hp 1320 laser printers was studied as two types of the most conventional laser printers. Due to lack of research, there is a little data about the organic pollutants produced by these instruments. So this study was evaluated in the glass box chamber based on the standard of ISO16000-9 for the first time and the samples were analyzed by Gas chromatography, mass spectroscopy and Fourier transform infrared spectroscopy to identify the organic pollutants. Particle Size Analyzer was used to determine the scale and the count of the particles exist in the glass box chamber. According to the results, the different particles (0.5-10 μm) and the different organic pollutatns were detected. Also, hp 1200 laser printer released more amounts of the fine particulate matters than hp 1320 laser printer but the amount of the organic pollutants released from hp 1200 laser printer was negligible in comparison with hp 1320 laser printer.
