NAME ^

Prima::PS::Printer - PostScript interface to Prima::Printer

SYNOPSIS ^

use Prima; use Prima::PS::Printer;

DESCRIPTION ^

Realizes the Prima printer interface to PostScript level 2 document language through Prima::PS::Drawable module. Allows different user profiles to be created and managed with GUI setup dialog. The module is designed to be compliant with Prima::Printer interface.

Also contains convenience classes (File, LPR, Pipe) for non-GUI use.

SYNOPSIS ^

        use Prima::PS::Printer;

        my $x;
        if ( $preview) {
                $x = Prima::PS::Pipe-> create( command => 'gv -');
        } elsif ( $print_in_file) {
                $x = Prima::PS::File-> create( file => 'out.ps');
        } else {
                $x = Prima::PS::LPR-> create( args => '-Pcolorprinter');
        }
        $x-> begin_doc;
        $x-> font-> size( 300);
        $x-> text_out( "hello!", 100, 100);
        $x-> end_doc;

Printer options ^

Below is the list of options supported by options method:

Color STRING

One of : Color, Monochrome

Resolution INTEGER

Dots per inch.

PageSize STRING

One of: Ainteger, Binteger, Executive, Folio, Ledger, Legal, Letter, Tabloid, US Common #10 Envelope.

Copies INTEGER
Scaling FLOAT

1 is 100%, 1.5 is 150%, etc.

Orientation

One of : Portrait, Landscape.

UseDeviceFonts BOOLEAN

If 1, use limited set of device fonts in addition to exported bitmap fonts.

UseDeviceFontsOnly BOOLEAN

If 1, use limited set of device fonts instead of exported bitmap fonts. Its usage may lead to that some document fonts will be mismatched.

MediaType STRING

An arbitrary string representing special attributes of the medium other than its size, color, and weight. This parameter can be used to identify special media such as envelopes, letterheads, or preprinted forms.

MediaColor STRING

A string identifying the color of the medium.

MediaWeight FLOAT

The weight of the medium in grams per square meter. "Basis weight" or or null "ream weight" in pounds can be converted to grams per square meter by multiplying by 3.76; for example, 10-pound paper is approximately 37.6 grams per square meter.

MediaClass STRING

(Level 3) An arbitrary string representing attributes of the medium that may require special action by the output device, such as the selection of a color rendering dictionary. Devices should use the value of this parameter to trigger such media-related actions, reserving the MediaType parameter (above) for generic attributes requiring no device-specific action. The MediaClass entry in the output device dictionary defines the allowable values for this parameter on a given device; attempting to set it to an unsupported value will cause a configuration error.

InsertSheet BOOLEAN

(Level 3) A flag specifying whether to insert a sheet of some special medium directly into the output document. Media coming from a source for which this attribute is Yes are sent directly to the output bin without passing through the device's usual imaging mechanism (such as the fuser assembly on a laser printer). Consequently, nothing painted on the current page is actually imaged on the inserted medium.

LeadingEdge BOOLEAN

(Level 3) A value specifying the edge of the input medium that will enter the printing engine or imager first and across which data will be imaged. Values reflect positions relative to a canonical page in portrait orientation (width smaller than height). When duplex printing is enabled, the canonical page orientation refers only to the front (recto) side of the medium.

ManualFeed BOOLEAN

Flag indicating whether the input medium is to be fed manually by a human operator (Yes) or automatically (No). A Yes value asserts that the human operator will manually feed media conforming to the specified attributes ( MediaColor, MediaWeight, MediaType, MediaClass, and InsertSheet). Thus, those attributes are not used to select from available media sources in the normal way, although their values may be presented to the human operator as an aid in selecting the correct medium. On devices that offer more than one manual feeding mechanism, the attributes may select among them.

TraySwitch BOOLEAN

(Level 3) A flag specifying whether the output device supports automatic switching of media sources. When the originally selected source runs out of medium, some devices with multiple media sources can switch automatically, without human intervention, to an alternate source with the same attributes (such as PageSize and MediaColor) as the original.

MediaPosition STRING

(Level 3) The position number of the media source to be used. This parameter does not override the normal media selection process described in the text, but if specified it will be honored - provided it can satisfy the input media request in a manner consistent with normal media selection - even if the media source it specifies is not the best available match for the requested attributes.

DeferredMediaSelection BOOLEAN

(Level 3) A flag determining when to perform media selection. If Yes, media will be selected by an independent printing subsystem associated with the output device itself.

MatchAll BOOLEAN

A flag specifying whether input media request should match to all non-null values - MediaColor, MediaWeight etc.
