Paxar Gold 6037EX - Manual (Page 17)

Printer Features 2-3
If the application writes to
♦ a display page other than the current one, the displayed
information does not appear until the application uses
vidSetPage to switch to the new display page.
♦ the current display page, the displayed information appears
immediately.
You may want the application to write messages longer than 20
characters to the display or have a command move the cursor.
If you use standard C functions such as printf , puts , and putc in
the application, the message wraps to the next line and the
cursor moves. The vid functions truncate the message if it
extends beyond the twentieth column and only vidPutCursor
moves the cursor.

♦ set the display speed
