Bar code Printer setting and code

Hi All,

I am writing code to print two barcode slip side by side. For that I set width as 10 cm and height 3.6 cm in report properties.

Images are added.
Problem getting:

1. After setting height and width, the paper orientation is changed as landscape, but I want it as portrait.
2. If I change paper size as A4, the two barcode is printed at bottom of the page, which leads to waste the paper.
3. Barcode is not getting scanned. May be due to not printed properly.


Please help me out.

How to set bar code printer setting i m define paper size then printer is selected Landscape by default and suppose i m select Portrait then size also be changed.
