The general flatbed printer system is composed of a PC and a dedicated S/W, which is inconvenient to use. In the end, there is a need for a technology that can easily and conveniently use various types of printing through simplification, smartization, etc. of a flatbed printer system configuration. That is, there is an increasing demand for multi-dimensional printer capable of printing on various types of materials with one printer and capable of printing various types of products. Therefore, in this paper, we developed a flatbed printer system capable of multi-dimensional printing using Head Encoder/Trigger control. To this end, we developed a flatbed printer that connects the internal module of the flatbed printer with an input type detection sensor and controls all operating states by the head encoder and head trigger signals of the printer through separate main controllers. Through this, the development and diffusion of IoT technology will expand the printer control of the smart environment to the developed form throughout the industry. It is expected to contribute to the development of the 3D printing industry in the future.

To analyzed the shape of Yellow Dots which appeared on the paper printed HP color laser printer, and analyzed the characteristic of Yellow Dots according to time, month, year and same printers. As a result, documents that printed in same printers had an identical Yellow Dots's shapes according to time, month, year. It was presupposed that was not embedded time and date information in HP Color LaserJet printers against Xerox, and printers which have different serial number had similar shapes but it was not identical Yellow Dots. Finally, it was found to be identical patterns in Yellow Dots of HP Color LaserJet printers used analysis. Depending on the results, it could understand HP's pattern. In the future, it will decipher patterns of Yellow Dots which have other informations to include other printer manufacturer.

Users of computer interfaced with the LAN use the same printer with time sharing. Alternatively, Hey use the multi-user printer interface to print in the office which can't have LAN system due to the great expenses. Otherwise they have to connect directly moving the printer to computer. In this papaer, we present a new printer interface equipment which can interface a printer and multi computers through wireless using the radio frequency of about 430MHz. The tranceivers of the equipment consist of two part: one part is installed in parallel port of computer and other part is installed in Centronix port of printer. Their maximum data rate is 9600bps and the communication area is about 50 meters in best case.

Recently, 3D printer technology has been attracting attention in various industrial fields, and research papers are being conducted to utilize 3D printers in the construction industry. Actual structures such as bridges and buildings are being printed to 3D printers, and various applications such as mock-up structures using 3D printers are being proposed. In order to utilize 3D printer technology in the construction field, a 3D model is required, and the 3D BIM data produced at the design stage can be printed by a 3D printers, saving the cost and time of 3D model generation. However, 3D BIM data often does not satisfy the conditions for 3D printer output, causing many errors on output. In this paper, authors propose a problem analysis for 3D BIM model output to 3D printer and a method for reducing errors in 3D printing process of 3D BIM model. In addition, this paper presents a practical application of 3D model output from 3D printer.

The proliferation of Information Technology and Business Automation become the mainstay of the growth of world printer market. Especially the demand for high speed printers increases drastically as the need for printing service station in networked computing environment grows. However outstanding research activities are seldom reported. Only efforts are currently focused on the printing quality and development of application programs for low or midium speed printers. This stimulates the research for high-speed printers. In this paper, we first defined the architectural components of high-speed printers so that the performance requirements can be satisfied. The individual impacts of each module on overall throughput are then elaborately analysed. Based on this result, we accomplished well-tuned system architecture which presents up to 163.52 PPM. Another contribution of this paper can be found in that this is one of the first articles that deal with the architecture and the performance of high-speed printers.

Generally, printers are common for users to use for public use over a wired or wireless local area network. The number of printers in the same network is increasing, and management of multiple printers is needed. To do this, a program that drives two or more printers and a computer connected by a wired or wireless network. When a computer's control department receives a print command for a designated file, it executes the steps of receiving status information from the printer, selecting the printer, and sending the print command execution. As a method of research, we presented a method for selecting differentiation from this study through prior art research and literature research. Therefore, the purpose of the study is to distribute smart print commands according to real-time status information of many printers to increase the efficiency of the printer's management, and to distribute print commands according to the cumulative and usable workload of many printers so that parts replacement of many printers can be instantaneously performed.

Libraries both in South Korea and abroad have been adopting 3D printers and related service. This indicates the need for documented 3D printer use policy to facilitate the service. This study investigates 3D printer use policies of libraries in Korea and best practices of the United States, and suggests contents for 3D printer use policies in Korea. The finding shows that Korean libraries with 3D printers did not have systematic and documented 3D printer use policies. After conducting content analysis of 16 best practices of 3D printer use policies from libraries in the United States, the authors identified five themes (purpose, users, procedures, limitations of use, and liability) and 21 sub-themes. The findings are informative for Korean libraries to develop 3D printer use policies and to understand various considerations in implementing 3D printer services.

포토프린터 업계가 디카 유저를 향해‘色’있는 유혹을 시작했다. 디지털카메라의 급속한 성장은 인터넷 블로그와 결합하여 이미지커뮤니케이션 문화를 생성하고 있다. 사진, 필름출력, 인화의 일방적인 프로세스를 거친 아날로그 시대에 비해 디지털카메라는 블로그 및 포토프린터를 통한 프린팅, 디지털/온라인 현상소 등 다양한‘Out-Put'을 생산 해내고 있다. 이제 단지 출력물을 뽑던 과거에서 디지털이미지를 표현해내는 창작물의 도구로 포토프린터는 거듭나고 있다. 이에 발맞춰 최근 삼성전자를 비롯한 한국 HP, 한국엡손, 롯데캐논, 한국코닥, 한국후지필름 등 이미지 프린팅 관련 업계들은 유저들의 소비성향에 맞춘 다양한 포토프린터를 선보이며 공격적인 마케팅을 펼쳐나가고 있어 귀추가 주목되고 있다.
