'The following example draws the text both horizontally
'and vertically centered on the host printer page
'Primary Code:
Local x, y, w, h, w2, h2 As Long
Local sText AS String
sText = "PowerBASIC" 'text to print
XPrint Attach Default 'select a printer (default in this case)
XPrint Get Client TO w, h 'get print client size
XPrint Text Size sText TO w2, h2 'get text size
x = (w-w2) / 2 'centered x-pos (left-right)
y = (h-h2) / 2 'centered y-pos (top-bottom)
XPrint Set Pos (x, y) 'set print position to centered x/y
XPrint sText 'draw the text on the printer
XPrint Close 'sends info to printer, sends formfeed, detaches host printer
