printers even though the PCL interpreter is emulating a simplex PCL printer. There are no switches that control how the image is shifted, because the DocuPrint sequencer does not perform image shifting on a page-by-page basis, but only on a job-by-job basis.

PCL 5 coding recommendations

When creating PCL 5 jobs, there are some general recommendations for optimal performance:

•Use PCL Fill Rectangle Area for horizontal and vertical lines and rectangles.

•

•

Use HPGL for other synthetic graphics (curves, diagonal lines).

Minimize raster usage (avoid translating fonts or lines into raster data); on fast (100Mbit) networks, send uncompressed data.

•

•

•

Maximize use of internal scalable fonts.

Define logos as fonts rather than raster graphics.

Rotate rasters to align with printer edge feed, using the Raster Graphics Presentation Mode, if possible.

•

•

Minimize switching between HPGL and PCL modes.

PCL 5c support

This section provides specific information related to the DocuPrint NPS implementation of PCL 5c on the 4850, 4890, 92C. For more information on PCL 5c, see the HP PCL 5 Color Technical Reference Manual.

The DocuPrint NPS implementation of PCL 5c is tuned for optimal print quality on the 4850, 4890, 92C highlight color printers.

Note: If the same document is printed with PostScript and with PCL 5c, the highlight color may not match exactly.

When the DocuPrint NPS PCL 5c interpreter is installed on the highlight color printers, the decomposer can switch between highlight color and monochrome modes dynamically on a per-job basis. You can specify monochrome printing (that is, Executive Black mode) by setting the highlight color attribute to black. The PCL 5e interpreter is used for monochrome mode.

In general, PCL 5c jobs can be expected to have much larger file sizes than PCL 5e jobs because of the nature of the PCL 5c driver. This is not a function of DocuPrint NPS.

The default highlight color rendering algorithm, Automatic, is not recommended for use with PCL 5c jobs. Presentation and Pictorial rendering algorithms produce the best appearance. The ColorToHighlight algorithm is also supported for PCL 5c.

For PCL 5c jobs, the Thicken attribute has no effect.
