USER  DEFINED PATTERNS

     
     In addition to the eight shading patterns and six cross
     hatch patterns, users can design their own patterns
     (area fill).  These user-defined patterns are
     downloaded to the printer.
     
     

USER DEFINED PATTERN PROGRAM EXAMPLE

     WIDTH "LPT1:",255             Prevents Basic from
                                   inserting an unwanted
                                   carriage return after 80
                                   characters are printed.
     
     LPRINT CHR$(27);"E";          Resets the printer.
     
     LPRINT CHR$(27);"*c32G";      Defines a pattern area
                                   fill ID number.
     
     LPRINT CHR$(27);"*c76W";      Gives the number of bytes
                                   used in the pattern.
     
     FOR I = 1 TO 76               Starts a loop of 76
                                   counts.

     READ A                        Reads a data point.
     
     LPRINT CHR$(A);               Tells Basic to print the
                                   current byte value.
     
     NEXT I                        Advances loop one step.
     
     DATA 20,0,1,0,0,16,0,32,,2,88,2,88 This is the header
                                   information for printer.
