Paxar Gold 6037EX manual S p l a y, Display Pages

D i s p l a y

The printer has an 8-row display. The printers can display characters in either reverse or normal video. A display backlight is also available.

Several functions that manipulate the display use a coordinate system to access a certain point on the display. Coordinate (0,0) (row, column) is the display’s upper-left corner.

The display is not compatible with any

standard IBM PC display adapter. There is

no program-accessible video memory.

Display Pages

The printer has two display pages (numbered 0-1).

An application can manipulate any display page, regardless of the current page. To manipulate the display, use the functions with the vid prefix (see Chapter 4, “Function Reference”).

Each display page has its own cursor. Only one page appears on the display at a time. To ensure the

♦application begins on the same display page every time, use vidSetPage to set the display page at the application’s beginning.

♦display pages are empty at the application’s beginning, use vidScroll to clear the pages at the application’s beginning and end.
