Graphics-Printing Program For The HP Paintjet Printer 3 - Restrictions on the complexity of the problem: For plotting on the IBM PC, the plotting emulator PCPLOT is needed These routines manipulate the pen movements on the screen and are also capable of capturing these same movements so that a hardcopy can be made to dot matrix or laser printer. 2 - Method of solution: The subroutines in the EZVIDEO system are based on the Hewlett Packard HP 9000 simulation of DISSPLA. The forerunner of EZVIDEO was called EZPLOT. Screen dumps can also be made to an attached LaserJet or Epson printer to make hard copy without using terminal emulators. Furthermore, it was found that the mixing ventilation system has a lower mean particle concentration in the breathing zone compared to the most displacement ventilation systems.ĮZVIDEO, DISSPLA Graphics Software Simulation on IBM PCġ - Description of program or function: EZVIDEO simulates a subset of the DISSPLA plotting package to make plots on the IBM PC screen. The results also showed that when the printer is located on the front side of the manikin, the particle concentration in the breathing zone is quite high in most of the used ventilation configurations. The results of the present study showed that in case of the heated manikin, the particle concentration due to the printer pollutants is significant in the breathing zone of the manikin. The averaged particle concentration in the breathing zone of the manikin was calculated and validated with the experimental and numerical data available in the literature. The printer was located on different sides of the manikin and the particle concentrations in the breathing zone of the manikin due to the printer’s particles were evaluated in all the ventilation configurations. Effects of different ventilation configurations of the room on the particle distribution were studied, including three displacement ventilation systems and a mixing ventilation system. A seated manikin was integrated into the study room and the manikin was evaluated in two cases: heated and unheated. Abstract: In the present research, computational modeling of particle transport and distribution emitted from a Laserjet printer was carried out in a ventilated room. • Mixing ventilation system has a low mean particle concentration in the breathing zone. • Effects of different ventilation configurations on the breathing zone concentration were investigated. Highlights: • The distribution of emitted particles form a laserjet printer was studied in the breathing zone.
