SAP script alignment issue

Hi Everyone,

i have a typical problem with scripts. i have to print sales invoice scripts. To print the SI im using SAP printer LOCL and had developed according to that printer. but if i use different printer say PD61 i face a alignment issues of the contents,the horizontal-vertical lines joining and font sizes differing, though i have used tabs to seperate..

please can anyone help me to develop scripts across printers. Thanks in advance.
