6 Prima::PS::Printer - PostScript interface to Prima::Printer
7
9 use Prima; use Prima::PS::Printer;
10
12 Realizes the Prima printer interface to PostScript level 2 document
13 language through Prima::PS::Drawable module. Allows different user
14 profiles to be created and managed with GUI setup dialog. The module is
15 designed to be compliant with Prima::Printer interface.
16 Also contains convenience classes (File, LPR, Pipe) for non-GUI use.

36 Below is the list of options supported by "options" method:
37 Color STRING
39 One of : "Color, Monochrome"
40 Resolution INTEGER
42 Dots per inch.
43 PageSize STRING
45 One of: "Ainteger, Binteger, Executive, Folio, Ledger, Legal,
46 Letter, Tabloid, US Common #10 Envelope".
47 Copies INTEGER
49 Scaling FLOAT
50 1 is 100%, 1.5 is 150%, etc.
51 Orientation
53 One of : "Portrait", "Landscape".
54 UseDeviceFonts BOOLEAN
56 If 1, use limited set of device fonts in addition to exported
57 bitmap fonts.
58 UseDeviceFontsOnly BOOLEAN
60 If 1, use limited set of device fonts instead of exported bitmap
61 fonts. Its usage may lead to that some document fonts will be
62 mismatched.
63 MediaType STRING
65 An arbitrary string representing special attributes of the medium
66 other than its size, color, and weight. This parameter can be used
67 to identify special media such as envelopes, letterheads, or
68 preprinted forms.
69 MediaColor STRING
71 A string identifying the color of the medium.
72 MediaWeight FLOAT
74 The weight of the medium in grams per square meter. "Basis weight"
75 or or null "ream weight" in pounds can be converted to grams per
76 square meter by multiplying by 3.76; for example, 10-pound paper is
77 approximately 37.6 grams per square meter.
78 MediaClass STRING
80 (Level 3) An arbitrary string representing attributes of the medium
81 that may require special action by the output device, such as the
82 selection of a color rendering dictionary. Devices should use the
83 value of this parameter to trigger such media-related actions,
84 reserving the MediaType parameter (above) for generic attributes
85 requiring no device-specific action. The MediaClass entry in the
86 output device dictionary defines the allowable values for this
87 parameter on a given device; attempting to set it to an unsupported
88 value will cause a configuration error.
89 InsertSheet BOOLEAN
91 (Level 3) A flag specifying whether to insert a sheet of some
92 special medium directly into the output document. Media coming from
93 a source for which this attribute is Yes are sent directly to the
94 output bin without passing through the device's usual imaging
95 mechanism (such as the fuser assembly on a laser printer).
96 Consequently, nothing painted on the current page is actually
97 imaged on the inserted medium.
98 LeadingEdge BOOLEAN
100 (Level 3) A value specifying the edge of the input medium that will
101 enter the printing engine or imager first and across which data
102 will be imaged. Values reflect positions relative to a canonical
103 page in portrait orientation (width smaller than height). When
104 duplex printing is enabled, the canonical page orientation refers
105 only to the front (recto) side of the medium.
106 ManualFeed BOOLEAN
108 Flag indicating whether the input medium is to be fed manually by a
109 human operator (Yes) or automatically (No). A Yes value asserts
110 that the human operator will manually feed media conforming to the
111 specified attributes ( MediaColor, MediaWeight, MediaType,
112 MediaClass, and InsertSheet). Thus, those attributes are not used
113 to select from available media sources in the normal way, although
114 their values may be presented to the human operator as an aid in
115 selecting the correct medium. On devices that offer more than one
116 manual feeding mechanism, the attributes may select among them.
117 TraySwitch BOOLEAN
119 (Level 3) A flag specifying whether the output device supports
120 automatic switching of media sources. When the originally selected
121 source runs out of medium, some devices with multiple media sources
122 can switch automatically, without human intervention, to an
123 alternate source with the same attributes (such as PageSize and
124 MediaColor) as the original.
125 MediaPosition STRING
127 (Level 3) The position number of the media source to be used. This
128 parameter does not override the normal media selection process
129 described in the text, but if specified it will be honored -
130 provided it can satisfy the input media request in a manner
131 consistent with normal media selection - even if the media source
132 it specifies is not the best available match for the requested
133 attributes.
134 DeferredMediaSelection BOOLEAN
136 (Level 3) A flag determining when to perform media selection. If
137 Yes, media will be selected by an independent printing subsystem
138 associated with the output device itself.
139 MatchAll BOOLEAN
141 A flag specifying whether input media request should match to all
142 non-null values - MediaColor, MediaWeight etc.
