Thx Deepak.
Now its printing continuously but page length didn't set properly might be. my paper size is 8.5 X 5.5.
So, in printer intialization i have mentioned the page length as \e\0x43\0x21 and in page format, landscape page format of size 216MM width and 140MM height.
even though one the print is not coming properly for multiple pages. The alignment is missing from one page to another in case of multiple pages.
Please suggest me how to avoid this...
Regards,
Venkat
