Specifying print format parameters

Options

Table 4-97. VFU TOF parameter options and definitions
Option	Definition
value	Specifies the number of lines from the top of the logical page to the first print
	line (top of form). The TOF specification is independent of channel
	assignments. It should be greater than or equal to 1, and less than or equal to
	the smallest line number assigned to a channel.
Default	1

VFU TOF If the value that is specified in the TOF parameter is greater than parameter: point or equal to the BOF (Bottom Of Form) value, the TOF value is set

to note to 1.

VFU command: points to note

• For all PCCTYPEs except ANSI and user defined PCCs, the prejob page alignment is with TOF in the expectation that the first carriage control parameter of the job will be Print and Space One Line, or something similar.

• Page overflow occurs when spacing to the next line causes the BOF line number to be exceeded. Page transition occurs, and line spacing continues from the TOF line number. (Xerox carriage control is an exception to this processing.)

• Any channel operation encountered during printing for an

unassigned channel causes a Print And Space 1 Line operation. This operation occurs even though some vendor formats normally specify the default as a Space 1 Line And Print operation.

• Multiple line numbers may be assigned to the same channel number. This simulates the vertical tabbing feature of an impact line printer where a Skip to Channel parameter causes transition to the next punched hole in the specified channel of the paper tape. This paper tape, which controls the printer, facilitates spacing a fixed number of lines down the print page. There may be multiple punches in any vertical format channel on the impact printer tape.

• A Skip to Channel parameter sent to the printing system causes it to select the next line number in the PCC ASSIGN list (for that channel) larger than the current line number. Page transition and alignment to the first line number in the list occur if no line number is larger than the current line.
