The [[_PRINTIMAGE]] statement prints a colored image on the printer, stretching it to full paper size first.

: [[_PRINTIMAGE]] {{Parameter|imageHandle&}}
|
|
|
|
|
|
|
|
* {{Parameter|imageHandle&}} is created by the [[_LOADIMAGE]], [[_NEWIMAGE]] or [[_COPYIMAGE]] functions.
|
|
* Use a white background to save ink. {{InlineCode}}[[CLS]] , _RGB(255, 255, 255){{InlineCodeEnd}} 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 [[_FONT]]s.
