LPRINT
[edit | edit source]Syntax
[edit | edit source]LPRINT [@(col,row)|%(h,v)] [itemList]
Description
[edit | edit source]This statement sends a line of text to the printer. The @(col,row) and %(h,v) options specify where on the page the line should be printed (see the PRINT statement); if you don't specify one of these, the line is printed at the current pen position of the printing grafPort (this is usually just under the previously-printed line).
The LPRINT statement is equivalent to the following group of lines:
ROUTE _toPrinter
PRINT [@(col,row)|%(h,v)] [itemList]
ROUTE _toScreen
LPRINT is inefficient if you are printing many lines to a page, because it reroutes the output each time LPRINT is executed. In such cases, it's better to execute a sequence of PRINT statements, with the entire sequence preceded by a single ROUTE _toPrinter statement and followed by a single ROUTE _toScreen statement.
FB Lite behavior:
When you use the "FB Lite" runtime, the text-position parameters [@(col,row)|%(h,v)] are ignored.
Note:
You should execute CLEAR LPRINT or CLOSE LPRINT in order to cause the printed page to be put out, after you have finished printing to it.
