Redirecting Fonts and Graphics to Printer with WINDOW OUTPUT#

MORE INFORMATION

For a description of which BASIC versions support the Apple ImageWriter I, II, or LQ, or the Apple LaserWriter, please query on the following words for a separate article in this database: The following is a code example:

OPEN "LPT1:" FOR OUTPUT AS #1         ' Opens printer as #1.
WINDOW OUTPUT #1            ' Redirects output to device #1.
REM  Perform any window output here (TEXTFONT, TEXTSIZE, PRINT,
REM  CIRCLE, PICTURE, ROM Routines, etc.) to redirect to the printer.
REM  Exceptions:  The BACKPAT ROM routine (and PUT in BASIC Interpreter
REM  2.00) is not redirected to the printer.
REM  The image must lie within coordinates (1,1)-(638,750)
REM  on the Standard ImageWriter printer.
TEXTFONT 4 : TEXTSIZE 9    ' Changes to Monaco font, size 9.
LOCATE 3,1
PRINT "This is in monaco font."
LINE (1,20)-(55,34),,b  ' Draws box.
CLOSE #1     ' The output won't print until you CLOSE #1.
				

Using this technique, you can send to the printer a much larger area than you can see on the screen. The maximum window that you can see on the standard Macintosh screen must lie within screen coordinates (1,21)-(510,338). By using the above program, you can print to window coordinates (1,1)-(638,750) on the ImageWriter (or LaserWriter) printer, corresponding to a full 8.5-inch x 11-inch printed page. An even larger area can be printed to the wide (15-inch) ImageWriter printer.
