Dear Expert,

I have done program to generate epay slips as PDF and mail to relevant users, I am using GET_PAYSLIP FM to convert pay slip to PDF And also I am using ZORD pay slip variant .my issue is when the mail comes to users its font size is too big and as a result of that it will go next page, is there any possibility to change variant font size??

Thanks in advance
