{{DISPLAYTITLE:_PRINTSTRING}}
The [[_PRINTSTRING]] statement prints text [[STRING|strings]] using graphic column and row coordinate positions.


{{PageSyntax}}
: [[_PRINTSTRING]]({{Parameter|column}}, {{Parameter|row}}), {{Parameter|textExpression$}}[, {{Parameter|imageHandle&amp;}}] 


{{Parameters}}
* {{Parameter|column}} and {{Parameter|row}} are [[INTEGER]] or [[LONG]] starting PIXEL (graphic) column and row coordinates to set text or custom fonts.
* {{Parameter|textExpression$}} is any literal or variable [[STRING|string]] value of text to be displayed.
* {{Parameter|imageHandle&amp;}} is the optional image or destination to use. Zero designates current [[SCREEN (statement)|SCREEN]] page.


{{PageDescription}}
* The starting coordinate sets the top left corner of the text to be printed. Use [[_FONTHEIGHT]] to calculate that text or [[_FONT|font]] position
* The [[_FONT]] size can affect the [[SCREEN (statement)|screen]] and row heights.
** Custom fonts are not required. [[_PRINTSTRING]] can print all [[ASCII]] characters.
* [[_PRINTWIDTH]] can be used to determine how wide a text print will be so that the screen width is not exceeded.
* If the {{Parameter|imageHandle&amp;}} is omitted, the current image, page or screen destination is used.
* Can use the current font alpha blending with a designated image background. See the [[_RGBA]] function example.
* Use the [[_PRINTMODE]] statement before printing to set how the background is rendered.
** Use the [[_PRINTMODE (function)]] to find the current _PRINTMODE setting.
* In SCREEN 0 (text only), [[_PRINTSTRING]] works as one-line replacement for '''LOCATE x, y: PRINT text$''', without changing the current cursor position.


==Availability==
* In versions of QB64 prior to 1.000 _PRINTSTRING can only be used in graphic, 256 color or 32 bit screen modes, not SCREEN 0.''

: ''Explanation:'' The procedure above creates a larger version of a SCREEN 13 window by stretching it with [[_PUTIMAGE]]. It cannot stretch PRINTed text so [[_PRINTSTRING]] must be used instead. [[LOCATE]] sets the PRINT cursor position for [[CSRLIN]] and [[POS]](0) to read. The SUB then converts the coordinates to graphical ones. Then '''change''' [[PRINT]] to PRINTS using the IDE '''Search Menu'''.
