Add border arond text in pdf

I have large database in text format.I convert them in particular format using awk. While using awk i have added escape sequence ^ for formatting in enscript like bgcolor,font,color etc. Then i convert same in pdf with ps2pdf command. In awk when i use printf "|%s|",$1 it is printing vertical line but breaked. I want different borders/boxes around various textfield. Whether it is possible to do with enscript OR ps2pdf OR pdftk ?
