Issue with printing Text in LNUI report

Hi,

I've customized a new report for Printing the Journal Voucher, While I print the report in the BW environment, it prints fine. But, while printing the same from the LNUI or selecting the device to print, as "pdf", I see that the text field is not getting printed properly. The lines in the text are getting repeated randomly according to its size. Getting confused, what went wrong. :confused:
Any leads would be highly appreciated.

Thank you.
