AST TURBOLASER / HARVARD PRESENTATION GRAPHICS
PROBLEM: When plotting a chart or graphics using TurboLaser
plotter emulations in HPGL mode, the output is printed in reverse
image. Diagrams, charts and characters are white on a black
background instead of black on a white background.
AST Systems Engineering attributes this problem to nonstandard
plotter commands being sent to the printer from the Harvard
Presentation program.
CONFIGURATION:
AST TurboLaser Model 800
Software Versions 1.10 or 1.21
HPGL Emulations HP 7440, 7470A, 7475A, 7510, 7550A
IBM 7371 and 7372
Harvard Presentation Graphics Revision A
IBM PC/AT, AST PREMIUM/286
ALTERNATE METHOD OF PRINTING:
The user can obtain a satisfactory output using the TurboLaser
Epson emulations and selecting the "High" resolution option for
printer output.
