CHAPTER 4 — PROGRAMMABLE FUNCTION STRINGS | Page |
This is not normally used with laser printers, and it is only used when some type of PFS Suppression is active or when Vertical Movement has been set to Line Feed. Normally, the 5250 OPTIMA sends the VERMOVE PFS to control all vertical movement.
PORT
Print page in portrait orientation. This PFS is sent to the printer at the beginning of all portrait pages, determined by the 5250 OPTIMA’s page orientation algorithm. This should cause the printer to enter a portrait page orientation and to select a default font for that orientation. If page orientation for the printer is selected by font, the user needs only to select the appropriate font.
LAND
Print page in landscape orientation. This PFS is sent to the printer at the beginning of all landscape pages, determined by the 5250 OPTIMA’s page orientation algorithm. This should cause the printer to enter a landscape page orientation and to select a default font for that orientation. If page orientation for the printer is selected by font, the user needs only to select the appropriate font.
VERMOVE
Move the printhead vertically. This is sent to the printer whenever the
5250 OPTIMA needs to position something vertically on the page, e.g., the beginning of a line of text or the top margin of a page. It is dependent upon two format options (under FMTINFO: in the configuration menu). If ABSOLUTE, the parameter specifies the vertical position to which to be moved. If RELATIVE, it provides the distance down to move. The unit of measure for the distance must also be supplied in the VER RES= option under FMTINFO: for the port.
The SCS commands that may affect this PFS include: Required New Line, New Line, Interchange Record Separator, Line Feed, Set Initial Conditions (top margin parameter), Set Vertical Margins (top margin parameter), Index Return, Absolute Vertical Print Position and Relative Vertical Print Position. The 5250 OPTIMA uses the ls parameter in the SCS Set Line Spacing command to calculate the vertical movement commands to send to the target printer.
