Dear All, Greetings. I am doing one project for Indian Meteorological Department Chennai [1] based on my college project [2]. The project is "Generating Change Chart" [3] and the project output is ready to implement. We need to take printout the output image. I installed ubuntu lucid 10.04 and CDAT in imdc machine to implement my project. They are taking many image printouts everyday from windows xp machine which is connected to HP Plotter via USB port. HP Plotter Model is HpDesignJet500ps. [4] & [5] I connected the ubuntu machine and windows machine via local network. The plotter is shared from windows to local network. I installed samba and cups in ubuntu. So that i can found the network printer via windows samba. If i give the print from ubuntu, it says printing process is sent and completed the job successfully. But the plotter does not printing the image. i.e the windows machine does not forward the printing job to HpPlotter . I stopped all firewalls in windows machine. How to approach this issue.
