The invention discloses printing data processing method, device and equipment as well as a storage medium. The printing data processing method comprises the following steps that logical channel parameters corresponding to logical channel serial number and the serial number of the current printing task are obtained according to the logical channel serial number; task parameters corresponding to thecurrent printing task and the printing position of the current printing task are obtained according to the current printing task serial number; according to the logical channel parameters, the task parameters corresponding to the current printing task and the printing position, a storage address of the channel data corresponding to the logical channel and printing parameters are obtained; and thechannel data are extracted from the print memory according to the storage address, and the channel data and the printing parameters are processed to obtain printing data. According to the printing data processing method, device and equipment as well as the storage medium, the image data can be simply, efficiently and correctly read out from the print memory without error.

The invention provides a jet printing spacing regulating and controlling method based on near field electrospinning jet printing multi-needle array experiments. The method mainly comprises the steps of: grounding a collector plate of an apparatus and electrically connecting a tip of an injector and a direct current high voltage; starting an electrostatic spinning system, wherein an X-Y-Z-U movingplatform begins to move according to a path planned by upper computer software so that an organic solvent forms a Taylor cone at the point of a jet head by the action of an electric field to realize array equally-spaced jet printing; rotating a rotary scale coded disc to drive and adjust array needle heads to rotate, so that angle adjustment is realized; calculating the demanded angle for rotationfor the array needle heads according to a formula (described in the specification), wherein x is the desired needle spacing and y is the actual needle spacing of the array needle heads. The method has the advantages of easy implementation, clear control logic and high precision.

The embodiment of the invention relates to the technical field of high-speed digital printing and discloses a synchronous data processing method and a synchronous data processing device for multi-nozzles and a printer. The device is applied to a field-programmable gate array device; the field-programmable gate array device includes a memory; the device comprises a data verification module, a dataanalysis module, a data caching module, a data splitting and distribution module and a nozzle driving module, wherein the data verification module is used for acquiring spray-printing data and verifying the spray-printing data; the data analysis module is used for acquiring the verified spray-printing data and analyzing the verified spray-printing data to generate analysis data; the data caching module is used for caching the analysis data into the memory; the data splitting and distribution module is used for acquiring the cached analysis data and splitting the cached analysis data into datablocks which have the same number as the nozzles; and the nozzle driving module is used for receiving the data blocks and driving the nozzles for data flow spray-printing. Therefore, when the plurality of nozzles exists, the data are enabled to be processed synchronously, and a spray-printing pattern is tidy and free of burr.

Synchronous data processing method and device for multi-nozzles and printer

A synchronous data processing apparatus and method for multiple print heads, and a printer. Said apparatus is applied to a field programmable gate array device, the field programmable gate array device including a memory, and includes: a data verification module (101) for acquiring print data and verifying the print data; a data parsing module (102) for acquiring the verified print data, and parsing the verified print data, so as to generate parsed data; a data cache module (103) for caching the parsed data in the memory; a data splitting and distributing module (104) for acquiring the cached parsed data, and splitting the cached parsed data into data blocks, the number of the data blocks being equal to the number of print heads; and a print head driving module (105) for receiving the data blocks and driving the print heads to print data streams. The apparatus, method, and printer ensure that data can be processed synchronously when a printer has multiple print heads, enabling a printed pattern to be neat and free of burrs.
