Optimizing Print Speed
69
OpenPrint Postscript/PDF Emulations
You can optimize print quality for darker and sharper text and barcodes by
using the following configuration parameters:
•
Unidirectional (Printer Control menu): Select “Enable” for best quality
but reduced throughput (half speed).
•
Resolution (Postscript/PDF menu): Select higher values (horizontal by
vertical DPI) to get better print quality.
H-Series Emulations
Print quality varies based on the typeface selected. Both text and barcodes
will print using the resolution of the selected typeface.
Optimizing Print Speed
LP+, IGP/PGL, and IGP/VGL Emulations
The printer has been configured at the factory for optimal print speed. To
optimize print quality instead, you can change values for specific configuration
parameters such as Barcode Quality and Print Quality. Doing so, however,
will decrease the printer speed.
If you have optimized the printer for print quality, you can change it to optimize
the speed by selecting the values as follows:
•
Bar Code Quality (Printer Control menu): Select Draft.
(See page 221 for the Printer Control Menu, and see page 222 for a
written description of Bar Code Quality.)
•
Print Quality (IGP/PGL emulation): Select Dataprocessing.
(See page 175 for the IGP/PGL Configuration Menu, and see page 182
for a written description of Print Quality.)
•
Print Quality (IGP/VGL emulation): Select Dataprocessing.
(See page 186 for the IGP/VGL Configuration Menu, and see page 190
for a written description of Print Quality.)
OpenPrint Postscript/PDF Emulations
The printer has been configured at the Factory for optimal print quality
through the Resolution configuration parameter (Postscript/PDF menu).
However, users can reduce the horizontal, vertical, or both DPI values of this
menu to increase printer speed. The downside of using a lower DPI value is
as follows:
•
Print quality is reduced and it can be difficult to read small characters.
•
Barcodes may not get detected and optimized (barcodes are not
searched for DPI values less than 120).
Users are encouraged to use the Resolution menu to find the right
combination of Print Quality, Barcode Optimization, and Print Speed.
