_PRINTIMAGE
The _PRINTIMAGE statement prints a colored image on the printer, stretching it to full paper size first.
Syntax
- _PRINTIMAGE imageHandle&
- imageHandle& is created by the _LOADIMAGE, _NEWIMAGE or _COPYIMAGE functions.
- Use a white background to save ink. CLS , _RGB(255, 255, 255) can be used to set the white background in any SCREEN mode.
- The image may be stretched disproportionately using normal screen sizes. To compensate, use a _NEWIMAGE screen that is proportional to the paper size. e.g. A 640 X 900 SCREEN page is roughly the same as 3 times a 210mm X 297mm paper size.
- _NEWIMAGE or graphic screen pages can use _PRINTSTRING to print different sized text _FONTs.
- Keyword Not Supported in Linux or MAC versions
Examples
Example 1: Shows how to transfer custom font text on screen pages to the printer in Windows. Change the font path for other OS's.
PageScale = 10 PageHeight = 297 * PageScale 'A4 paper size is 210 X 297 mm PageWidth = 210 * PageScale Page& = _NEWIMAGE(PageWidth, PageHeight, 32) _DEST Page&: CLS , _RGB(255, 255, 255): _DEST 0 'make background white to save ink! CursorPosY = 0 'example text to print PointSize = 12 text$ = "The rain in Spain falls mainly on the plain." GOSUB PrintText PointSize = 50 text$ = "BUT!" GOSUB PrintText PointSize = 12 text$ = "In Hartford, Hereford, and Hampshire, hurricanes hardly happen." GOSUB PrintText INPUT "Preview (Y/N)?", i$ 'print preview of screen (optional) IF UCASE$(i$) = "Y" THEN Prev& = _NEWIMAGE(600, 900, 32) 'print preview smaller image _PUTIMAGE Page&, Prev& SCREEN Prev& DO: LOOP UNTIL INKEY$ <> "" SCREEN 0 END IF INPUT "Print on printer (Y/N)?", i$ 'print screen page on printer IF UCASE$(i$) = "Y" THEN _PRINTIMAGE Page& END IF END PrintText: FontHeight = INT(PointSize * 0.3527 * PageScale) FontHandle = _LOADFONT("c:\windows\fonts\times.ttf", FontHeight) _DEST Page& _FONT FontHandle COLOR _RGB(255, 0, 0), _RGBA(0, 0, 0, 0) 'RED text on clear black background _PRINTSTRING (0, CursorPosY), text$ _FONT 16 'change to the QB64 default font to free it _FREEFONT FontHandle _DEST 0 CursorPosY = CursorPosY + FontHeight 'adjust print position down RETURN
- Explanation: CLS with the color white makes sure that the background is not printed a color. The PrintText GOSUB sets the COLOR of the text to red with a transparent background using _RGBA to set the _ALPHA transparency to zero or clear black.
Example 2: Printing an old SCREEN 12 ASCII table using a deeper sized page to prevent stretching by _PRINTIMAGE.

- Explanation: The ASCII character table was originally made in SCREEN 12 (640 X 480) and was adapted to 256 colors.
