Printing an ECG continuously

Wow. You should have edited your post, not created a new one with my name on it. What if I was not reading when you posted it ?

Mr Graus...I want to print instantly i.e. when an arc is drawn, the same arc should be printed on the printer in the same way when another arc is drawn is drawn it should also be printed on the paper ahead of the previous arc...

It doesn't work that way. It's not a plotter, it's a printer. It prints top down, then it ejects the page when the page is done.

As u suggests,to use e.circle then it draw circle and it would print the whole circle, is not my requirement...it want to print like ECG which sends heart beat to the printer instantly and it continuous to print on every instant...

I'm not sure how an ECG relates to printing parts of a circle.

I hope u would understand more clearly by ECG mechanism...

I know what an ECG is. As it happens, my software has a number of ECG animations in it.

The best way I can see to do this, is to store ECG data until you have a page full, then print that page. Printing progressively MAY work, if the print job can just stay open, but you have to realise that all the printing needs to take place in the same call of the print routine, and it can only print top down, unless you're using a plotter, the page cannot be pulled back to print again on the same area.
