ADJUSTING PRINT QUALITY AND SPEED

Setting page order

DocuPrint delivers documents with the pages face down in the order presented in the Page Description Language. The order can be changed by setting the PageOrder attribute.

If the Staple attribute is set, DocuPrint must deliver the document face up. In order to deliver the stapled document in the correct order, it must image the document in reverse page order. In order to image a document in reverse page order, the entire document must be processed before printing starts.

For the best print speed, ensure that each PostScript program has the pages in the correct order for the finishing requirement for the document:

•No finishing is required: PDL should be in ascending page order. PageOrder attribute should be set to ascend.

•

•

Stapling is required: PDL should be in descending page order.

Duplex printing is required: there should be an even number of pages. Page order should be set to descend.

Note: If you are using a third-party finishing device connected to DocuPrint by a bypass transport, the page delivery order is determined by the requirements of the third-party device (face up or face down). To maximize performance, place the pages in the PostScript master in the order in which they are required by the finishing device.

Product features that affect print quality

You can improve the appearance of your documents by being aware of potential problems created through the use of proprietary PostScript extensions and device-dependent operators.

Proprietary PostScript extensions

When PostScript masters that use proprietary PostScript extensions to enable printer-specific features are printed on different PostScript printers, there may be appearance inconsistencies. For example, some versions of the Apple Macintosh PostScript driver download encrypted proprietary image “smoothing” operators to Apple LaserWriters. The downloaded PostScript code uses the product operator to determine if it is being used on a LaserWriter. If not, the proprietary code is bypassed by doing a flushfile. This allows the PostScript master to print on non–LaserWriter products. As a result, PostScript masters generated on a Macintosh with Apple proprietary features may produce output that varies between LaserWriter and non–LaserWriter PostScript printers.
