SCS Commands Supported by the ULTRA

Application programs running on the host computer generate data streams that contain both the data to be printed and the SCS commands that control the positioning of the data on the page, as indicated below. This section discusses how to use the SCS commands supported by the ULTRA.

Backspace (BS) — 16h

The Backspace command moves the presentation position horizontally one position to the left. If already at the leftmost position, this command results in no operation. Upon receipt of an SCS 16h in the data stream, the ULTRA will send an ASCII BS (08h) to printer, if the print position is not already at the left margin.

End of Message (EM) — 19h

An End of Message generates a new line, except when it occurs in the first printing column, dependent upon the setting of Option 52.

Form Feed (FF) — 0Ch

The Form Feed command moves the presentation position to the top and left margins of the next page.

Horizontal Tab (HT) — 05h

The Horizontal Tab command moves the presentation position horizontally to the next tab stop to the right. The horizontal tab stops are determined by the Set Horizontal Format command. Tab commands are translated into the appropriate number of spaces and sent to the printer. If there are no horizontal tab stops to the right of the current position, the HT is treated as a space character.

Interchange File Separator (IFS) — 1Ch

One of four Interchange Separator Commands used to delimit information strings in SCS data streams. The ULTRA interprets it as a space.

Interchange Group Separator (IGS) — 1Dh

The ULTRA interprets this Interchange Separator as a space.
