Description

A kind of page spinning solution of print job

Technical field

The invention belongs to graph image and print the field, be specifically related to a kind of page spinning solution of print job.

Background technology

In the prior art, print out equipment provides two kinds of paper feed modes usually, is called LEF (LongEdge Feed, long limit paper feed) and SEF (Short Edge Feed, the minor face paper feed), the paper of these two kinds of paper feed modes shows as horizontal placement and vertical the placement respectively in the paper groove.Because paper will carry out sub-image transfer printing and follow-up steps such as photographic fixing through transfer drum in the print procedure in printer, a kind of method that improves print speed is exactly to reduce the path of print paper in movement, so the high speed movement provides LEF and SEF dual mode usually, wherein the path of paper in movement is shorter under the LEF mode, and print speed is very fast.The same with the paper placement of SEF as LEF, the scan-data that dual mode requires also differs 90 degree or 270 degree, and this work is finished when data are provided by print control unit.

Many functions during printing are all relevant with rotation, and wherein bookbinding form is the most complicated a kind of.Provide behind the seal of bookbinding function equipment generally can only provide preceding 1 nail, in 2 nails and three kinds of modes of back 1 nail, but when offering application program, generally need provide a left side 1 nail, right 1 nail, a left side 2 nails, right 2 nails and last 2 nails, to be user-friendly to.The mode of these logics all is that rotation back uses three kinds of modes of movement to export to finish.

Because rotation mode is so important, the print system of existing different location solves in different ways.In the low side printer, a kind of mode among LEF or the SEF is only supported in employing usually, makes troubles to use; Also have some low side printers to adopt and the similar mode of high-end system, promptly adopt special chip that dot matrix is rotated, otherwise speed is difficult to accept, because the monochromatic dot matrix of an A4 600DPI breadth will the 16M internal memory, and high-grade movement generally adopts the multidigit interface, and printing one page under 8 interface case just needs the 128M internal memory.The employing special chip not only can increase the cost of print system, and in the environment of an employing rasterizer module (RIP), the mode of special chip can't be adopted.

If a kind of method can provide the rotation processing before rasterizer module is handled, when generating dot matrix, rasterizer module finishes rotation simultaneously, can satisfy simultaneously the rotation of complicated logic gutter pos, so not only can address the above problem, and can reduce the cost of print system.

Summary of the invention

At the defective that exists in the prior art, the objective of the invention is before rasterizer module is handled, promptly can calculate the page anglec of rotation, automatically adapt to the requirement of long limit paper feed and minor face paper feed and the rotation requirement of adaptation bookbinding operation simultaneously, and also be applicable to the function that other requires page rotation.

For reaching above purpose, the technical solution used in the present invention is: a kind of page spinning solution of print job may further comprise the steps:

(1) long limit paper feed and the minor face paper feed of at first hiding movement distinguished;

(2) print manager is checked job parameter, judges that operation is simple process minor face paper feed or long limit paper feed or needs special rotation to calculate;

(3) if operation is simple minor face paper feed or long limit paper feed, what promptly do not need special rotation, print manager to judge to place in the paper groove of movement is long limit paper feed or minor face paper feed, if long limit paper feed, revolve and turn 90 degrees, otherwise the anglec of rotation is 0, if not start of equipment, perhaps because could communication, then handle according to long limit paper feed, specify during output and use long limit paper feed paper according to the principle of quick output;

(4) if operation needs special rotation to calculate, the spinfunction according to operation requires to calculate the anglec of rotation so, and the requirement according to operation spinfunction self is rotated then;

(5) utilize the anglec of rotation control rasterizer module that calculates to carry out rasterisation, print manager is issued movement with operation dot matrix and job instruction, the movement print job.

Furthermore, in the step 4,, then calculate the anglec of rotation, may further comprise the steps with following method if operation needs special rotation to calculate:

1) print manager is at first judged the paper groove of operation, if the paper groove is for specifying the paper groove, the paper type that operation is set is the paper type of placing in the paper groove, be long limit paper feed or minor face paper feed, otherwise, according to the paper groove in the current communication situation of the movement size match paper groove, if can't communication or can not find the paper of coupling, selecting the paper groove is the highmulti paper groove, and the paper type that operation is set is long limit paper feed, guarantee output fast, otherwise the designated paper type is the paper groove type of placing in the paper groove;

2) according to the paper of operation appointment be the logical page (LPAGE) of long limit paper feed or minor face paper feed, operation be laterally or vertically and the bookbinding option search predefined rotation angle kilsyth basalt, determine the anglec of rotation of operation.

Effect of the present invention is: when handling long limit paper feed and the operation of minor face paper feed and needing the operation of special spinfunction, can avoid front-end software to see the paper type that to understand, and can before rasterizer module, calculate the anglec of rotation, avoid the time-consuming operation of rotation dot matrix or used special chip.
