Top margin

The total space at the top of the printed page. The top margin

 

is the sum of the top-of-form setting, the software-specified top

 

margin, and the printer’s TOP-MRG setting.

Top-of-form (TOF)

Tractor feed

Unidirectional printing

The logical top of the physical page, as “understood” by the printer when loading paper. The default TOF settings are 1 inch (25.4 mm) for both cut sheets and continuous forms.

A method for feeding continuous forms forward for printing. Holes on the sides of the forms fit over sprockets on two tractors located inside the printer. The forms are pulled for bottom feeding and pushed for rear feeding.

Printing is performed in one direction only, left to right. Unidirectional printing is slower than bidirectional printing, but the vertical alignment is more accurate. Unidirectional printing is useful when precise vertical alignment is required, as in ruled tables.
