When a page size is set in a layout, dashed lines appear to show the page limits.
If layout parts extend past these limits, two things can happen.
A single record printed will print two pages, one blank.
A series of records printed will slowly extend each page.
I have checked the layout and all fields are within the page size I am using an Oki Microline 5590 24 pin with listing paper and each page starts printing at the top about 2mm down each page a single record only print one page no blank page.
