PostScript

The StreamServe PostScript driver supports PostScript Level 2.

Image compression

Images are compressed using:

•	CCITT compression for 1-bit monochrome images

•	LZW (Lempel-Ziv-Welch) compression for grayscale and color images (i.e. all but 1-bit monochrome images).

The appropriate compression method is selected automatically according to image type. To further optimize image output for non-color printers, set the Grayscale option to Yes.

PostScript forms

PostScript forms can be used to optimize driver output. A form is a resource that can be added to the output stream once, cached in the printer memory and then executed multiple times on subsequent pages. This means that only information that changes between forms needs to be interpreted for each page. Images (raster and EPS), device overlays (EPS), and LXF overlays can be converted into forms.

Note:

Dynamic overlays from PreformatIN can not be converted into forms since they only appear once in the printed file.

Settings
Page size	Page size. If you select None, the printer device settings will be used when printing. Note: If you use a sheet layout definition, the sheet layout settings will override the driver settings.
Simplex/Duplex	Select whether to print on one side or both sides of the paper. If you select None, the printer device settings will be used when printing. Note: If you use a sheet layout definition, the sheet layout settings will override the driver settings.
Orientation	Print orientation. If you select None, the printer device settings will be used when printing. Note: If you use a sheet layout definition, the sheet layout settings will override the driver settings.
For	The name of the user for whom the document is printed.
Routing	Information about how to route the document back to its owner after printing, for example an email address.
Version	The version or revision number of the document or resource.
Page order	None – Select this option if the order of the pages is not important. Ascend – The pages of the document are in ascending order. Descend – The pages of the document are in descending order. Special – The pages in the document are in a special order, e.g. signature order and should not be changed.
Grayscale	Yes – Converts color images into 8-bit grayscale and compresses them using the LZW compression method. Select this option to optimize image output for non-color printers. No – The compression method is selected automatically.
Use PostScript forms	Yes – All static images and overlays used in the Project are generated as PostScript form objects. No – All data is processed as usual.
Virtual Memory for Forms (KB):	The amount of virtual memory to be used for forms. The default form cache size is 16 MB (16384 kB). If the amount of cached PostScript data exceeds the limit defined for this setting, the image or overlay will not be cached and will be processed as usual.
Copies	Not applicable.
