Not able to change font

Question

Hi ,
We need to print some text data in printer. As we print a report, with numbers, and columns, we need font widht to be constant for all the charecters for producing properly aligned reports. [ like in courier or monospace fonts]. In the code below, I am not able to set the font for my printer. In the print() method, I tried to set font as monospace for the graphics object, but it did not have any effect. It looks like it always print with Ariel font. For displaying in layouts, it works find. But not with printer. Please help.

I don't see how it would have worked on the screen. Is that what you meant by "For displaying in layouts, it works find."? You never called setFont(...) on the Graphics or Graphics2D object in your paint method. Use g2d.setFont(new Font("Monospaced", Font.PLAIN, size)) and you should be fine.
