6.1. INTRODUCTION Printers Are Output Devices Used to Prepare
P a g e | 1 MAINTENANCE OF COMPUTER SYSTEM LEARNING OBJECTIVES: Concept of printers. Study of printing mechanism. Study of dot matrix,inkjet and laserprinters. Concept of printer controller. To know about interface and signals. CHAPTER-6(PRINTERS) 6.1. INTRODUCTION Printers are Output devices used to prepare permanent Output devices on paper.Printers can be divided into two main categories : Impact Printers : In this hammers or pins strike against a ribbon and paper to print the text. This mechanism is known as electro-mechanical mechanism 6.2 PRINTING MECHANISM: There are two types of printers. 6.3 Impact printers An impact printer makes contact with the paper. It usually forms the print image by pressing an inked ribbon against the paper using a hammer or pins. Following are some examples of impact printers. 6.3.1Dot-Matrix Printers The dot-matrix printer uses print heads containing from 9 to 24 pins. These pins produce patterns of dots on the paper to form the individual characters. The 24 pin dot-matrix printer produces more dots that a 9 pin dot-matrix printer, which results in much better quality and clearer characters. The general rule is: the more pins, the clearer the letters on the paper. The pins strike the ribbon individually as the print mechanism moves across the entire print line in both directions, i-e, from left to right, then right to left, and so on. The user can produce a color output with a dot- matrix printer (the user will change the black ribbon with a ribbon that has color stripes). -
A Context and Taxonomy for Printing: Intersections of Culture and Technology, 1850-2000
A context and taxonomy for printing: Intersections of culture and technology, 1850-2000 This project is based upon a research funding application being made to the UK Arts and Humanities Research Council (AHRC), the body responsible in the UK for funding University research in this area. It has been written by myself, Stephen Hoskins and Paul Thirkell in response to a series of discussions at the last AEPM General Meeting in Odense, Denmark and in particular response to Alan Marshall’s paper at that meeting. Unfortunately there have been problems in submitting this application, partly because of the pressures of daily life, which fall upon us all, but primarily because of the (AHRC) body closing its application process for 12 months and the ongoing funding crisis in UK universities. However the AHRC is now open to fresh bids, if there are still enough museums interested Research Context: As observed by Alan Marshall in 2008,1 ‘in the 1960s, before the extraordinary eruption of digital techniques in the graphic arts, no one, not even the best informed commentator could have imagined the desktop publishing and digital prepress techniques which we take for granted…’ Forty years later, we are in a position to put the apparently unique phenomenon of the digital revolution into its broader technological, historical and social perspective. However, there has been little analysis of the technical developments, social impacts, and market shifts that led up to the present domination of digital printing. The printing museum offers an entirely appropriate forum for understanding the core events that have culminated in the digital revolution. -
Other Printing Methods
FLEXO vs. OTHER PRINTING METHODS Web: www.luminite.com Phone: 888-545-2270 As the printing industry moves forward into 2020 and beyond, let’s take a fresh look at the technology available, how flexo has changed to meet consumer demand, and how 5 other popular printing methods compare. CONTENTS ● A History of Flexo Printing ● How Flexo Printing Works ● How Litho Printing Works ● How Digital Printing Works ● How Gravure Printing Works ● How Offset Printing Works ● What is Screen Printing? ● Corrugated Printing Considerations ● Flexo Hybrid Presses ● Ready to Get Started with Flexo? 2 A History of Flexo Printing The basic process of flexography dates back to the late 19th century. It was not nearly as refined, precise, or versatile as the flexo process today -- and can be best described as a high-tech method of rubber stamping. Printing capabilities were limited to very basic materials and designs, with other printing methods greatly outshining flexo. Over the past few decades flexo technology has continuously evolved. This is largely thanks to the integration of Direct Laser Engraving technology, advancements in image carrier materials, and in press technologies. These innovations, among others, have led to increased quality and precision in flexo products. These technological improvements have positioned flexography at the helm of consumer product and flexible packaging printing. Flexo is growing in popularity in a variety of other industries, too, including medical and pharmaceutical; school, home, and office products; and even publishing. How Flexo Printing Works Flexo typically utilizes an elastomer or polymer image carrier such as sleeves, cylinders, and plates. The image carrier is engraved or imaged to create the design for the final desired product. -

Embodied Community and Embodied Pedagogy
ZINES, n°2, 2021 MATERIAL MATTERS: EMBODIED COMMUNITY AND EMBODIED PEDAGOGY Kelly MCELROY & Korey JACKSON Oregon State University Libraries and Press [email protected] [email protected] Abstract: In this essay, we outline how materiality can be a tool of critical pedagogy, leading to pleasure, vulnerability, and embodied learning in the classroom. Over the past four years, we have taught an honors colloquium to undergraduate students focused on self-publishing as a means to create social change. As we explore various publishing media, genres, and activist movements with our students, we combine traditional academic activities like scholarly reading and written analysis with informal hands-on craft time. Our students make collages, learn to use the advanced features on a photocopier, and collaborate on hectograph printing among other crafts, all as they begin to put together their own final DIY publication. Students regularly report that the hands-on activities are crucial to their learning, giving them new appreciation for the underground publications they read, through embodied experiences that can’t be replicated with a reading or a quiz. It also builds our community of learners, as we share ideas, borrow glue sticks, and chit-chat as we put our zines together. We will outline how we built and teach this course, placing it within our critical pedagogy – informed by bell hooks, Kevin Kumashiro, and Paulo Freire, among others – and how teaching this course has helped us incorporate embodiment into our other teaching. Keywords: embodied pedagogy, teaching, publishing. 58 Material Matters: Embodied Community and Embodies Pedagogy ZINES, n°2, 2021 INTRODUCTION Alison Piepmeier has argued that, “Zines’ materiality creates College, this course is one of a suite of course offerings community because it creates pleasure, affection, allegiance, and that highlight exploratory discovery and deep dives vulnerability” (2008, 230). -

Dick Maggiore: What We Can Learn from Xerox
Dick Maggiore: What we can learn from Xerox Tuesday Posted at 7:42 AM Company failed (and failed again) when it strayed from its established core position. By Dick MaggioreSpecial to The Canton Repository The basic positioning principle applies regardless of the size of your business or whether you sell to consumers or other businesses. It also does not matter whether your business sells locally, regionally or nationally, or whether you are for-profit or nonprofit. Your business works best when your brand stands for one idea. That's just the way the minds of your prospects and customers work. Xerox is a remarkable example of a company that did just about everything right in terms of technology, but made many mistakes in go-to-market matters. On the plus side, Xerox built one of the most powerful brands in the world. It achieved this by standing for one idea. Its name became the synonym for the act of making a photocopy, as well as the photocopy itself — the verb and the noun. Not too many brands can claim generic ownership of the category itself. In my industry, one of our favorite pastimes has been watching our friends at Xerox. Their follies demonstrated valuable lessons for business. In 1959, Xerox introduced the Xerox 914, the first automatic copier. Research showed people were not willing to pay 5 cents per copy, but Xerox launched the 914 anyway. The rest is photocopier history. If Xerox had heeded its research, it would have missed a tremendous opportunity to build the world’s greatest photocopier brand and gain notoriety as "the most successful product ever marketed in America" as Forbes magazine declared. -
