Title: Traditional Electronic Printing On The Internet


1
Traditional Electronic Printing On The Internet
  • William J. Bill McCalpin
  • EDPP, CDIA, MIT, LIT
  • Principal, MHE

2
  • Xplor 21st Global Conference and Exhibit
  • Miami Beach, Florida
  • October 30, 2000

3
Printing Versus The Internet
4
Printing Versus The Internet
  • Electronic printing is an 125,000,000,000 (US)
    industry worldwide (www.xplor.org)
  • There are now an estimated 98,685,000 host
    computers on the Internet (www.mids.org)
  • Xplor International estimates that the production
    of paper documents and electronic documents is
    still increasing
  • So, for a while yet, were living in a hybrid
    world

5
Printing Versus The Internet
  • Customer service needs identical look and feel in
    paper and electronic documents
  • Regulatory agencies continue to have an interest
    in document presentation
  • Customers need a re-education process as
    documents change media
  • Hence, there are good reasons in the short run to
    be concerned about presentation

6
The Nature Of Print Streams
7
EBCDIC Versus ASCII
  • BCD - Binary Coded Decimal
  • BCDIC - Binary Coded Decimal Interchange Code
  • EBCDIC - IBM Extended Binary Coded Decimal
    Interchange Code
  • ASCII - American Standard Code for Information
    Interchange

8
EBCDIC Line Data
  • EBCDIC encoded - 8 bit
  • Record-oriented because of IBM OSs
  • Carriage controls
  • Machine carriage controls
  • ANSI carriage controls

9
ASCII Line Data
  • ASCII encoded - 7 bit
  • Record orientation is not intrinsic to OS
  • Text files use print controls to delimit records
  • Common print controls
  • x0d carriage return
  • x0a line feed
  • x0c form feed

10
The EBCDIC Family Tree
  • EBCDIC text
  • 1403 data - EBCDIC records with a carriage
    control
  • LCDS - Line conditioned data stream
  • 3800 Mod I
  • 3211 data with Xerox DJDEs
  • Others
  • AFP, MODCA, and IPDS

11
The ASCII Family Tree
  • ASCII text
  • ASCII text with print controls
  • ASCII text with escape sequences
  • Epson MX-80 Xerox UDK (XES)
  • QMS QUIC IBM PPDS
  • HP PCL Xerox Metacode
  • Print programming languages using ASCII
  • Interpress PostScript

12
Line Data And Conditioned Line Data
  • 1403, 3211, other EBCDIC line data streams,
    including Xerox DJDE
  • 3800 Mod I and other IBM data streams
  • ASCII text files of all sorts

Print Data With Escape Sequences
  • Epson and many other impact printers
  • Xerox UDK (XES)
  • QMS QUIC

15
The Nature Of Internet Formats
16
Common Internet Formats
  • The most commonly used data format on the
    Internet is HTML - HyperText Markup Language
  • The next expected wave on the Internet is XML
    (eXtensible Markup Language) and its related
    standards such as XSL, SVG, etc.
  • As a secondary standard, PDF is widely used to
    present static documents

17
HTML
  • HTML is an instance of SGML
  • HTML has a set of 40 to 50 tags, which are
    grammar based
  • HTML tags have default presentation
    characteristics, but these can be overridden with
    CSS (Cascading Style Sheets)

18
Sample HTML
  • lt!doctype html public "-//w3c//dtd html 4.0
    transitional//en"gt
  • lthtmlgt
  • lth1gtPoison Ivy Vineyardslt/h1gt
  • ltpgtPoison Ivy Vineyards is an experiment in
    growing wine-quality grapes in a backyard in a
    residential neighborhood in Richardson, Texas.
    This website serves as a running diary of the
    steps I took to create the vineyard and -
    eventually - to make wine.lt/pgt
  • lt/htmlgt

19
XML
  • XML is eXtensible Markup Language, which means
    that you can make up the tags
  • Since a browser cant know how to format the
    tags, default formatting is in outline form
  • Normally, you would use XSL (CSS) to describe how
    each tag is to be formatted

20
Sample XML

22
PDF
  • PDF is Adobes Portable Document Format
  • PDF is a print stream, not an SGML instance
  • PDF is similar to PostScript, but more portable,
    because it carries its own resources
  • PDF provides good fidelity, at a price

  • PDF-1.1

Methods Of Moving Traditional Electronic Print To
The Internet
30
Five Methods
  • Conversion to PDF
  • Rasterization to gif or jpeg
  • Recomposition into HTML/XML
  • Conversion to normal HTML/XML
  • Translation to highly formatted HTML/XML

31
Conversion to PDF
  • This is a print stream to print stream conversion
  • The output in PDF usually looks very similar to
    the original printed document
  • Many tools which create the PDF also add value,
    such as hypertext links, bookmarking, et cetera,
    to the PDF document

32
Pros And Cons Of PDF
  • Pros
  • High fidelity to original document
  • Reader is widespread and free
  • Reasonably transportable
  • Widely used in some circles (e.g., IRS)
  • Cons
  • PDF files tend to be large
  • PDF documents are paper-sized centric
  • Browser requires a plug-in

33

  • PDF-1.1

  • ltlt
  • /CreationDate (D19960809191047)
  • /Producer (Acrobat Distiller 2.1 for Windows)
  • /Creator (Adobe PageMaker 6.0)
  • /Author (Doc)
  • /Keywords ()
  • /Title (bills)
  • /Subject ()
  • gtgt
  • endobj

34
Sources For To PDF
  • Composition Tools - create new PDF documents from
    source code
  • Transforms - translate existing formatted print
    streams into PDF
  • Larger Systems- composition or translation
    capabilities inserted transparently into document
    systems
  • See Xplor Products and Services Reference Guide

35
Rasterization to gif or jpeg
  • The print stream israsterized, that is,
    converted to a bit map format
  • GIF Graphical Interchange Format (GIF) -
    Invented by CompuServe for graphics. Supports
    only 256 colors, or 8 bits.
  • JPEG (Joint Photographic Experts Group)
    Specifically for more than 256 colors, with
    better compression, but is lossey
  • Excellent discussion of each at
    http//www.efuse.com/Design/web_graphics_basics.ht
    ml

36
Pros And Cons Of Rasterization
  • Pros
  • Image is exact copy of original document
  • Image can be viewed on any browser which takes
    gifs and jpegs
  • Cons
  • Resolution is hardcoded at one size
  • Theres no text to search
  • Download is longer
  • No correspondence of printed pages and HTML
    pages

37
Sample Rasterization
  • This page was originally created in PDF, then
    rasterized, and converted to a jpeg

38
Recomposition into HTML/XML
  • Data is extracted from a print stream
  • Templates have been created in advance
  • The extracted data is merged into the templates
  • There may be fewer or more output pages in HTML
    than were in the print stream
  • Templates are built to be the most effective in
    the browser window

39
Pros And Cons Of Recomposition
  • Pros
  • HTM/XMLL pages are well-suited for the browser
  • HTML/XML is considered by some to be simpler than
    PDF
  • Cons
  • HTML/XML pages dont necessarily match the
    printed pages
  • All pages (templates) must be pre-composed

40
Sample Recomposition
  • This document is a sample telephone bill which
    have been divided into 11 HTML pages
  • Note how the HTML pages are divided by subject,
    not by page overflow

41
Conversion to normal HTML/XML
  • Both data and formatting information are
    extracted from the print file
  • Some formats easily correspond to an HTML tag,
    e.g., a heading to lth1gt
  • More complex formatting can be approximated by
    the use of table tags

42
Pros And Cons of Conversion
  • Pros
  • HTML/XML pages look similar to printed pages
  • Pages are in HTML/XML, not PDF or raster
  • Cons
  • Fidelity is approximate
  • Reader can substantially alter the presentation
  • Graphics may not be supported

43
Sample Conversion
44
Translation to highly formatted HTML/XML
  • This method uses particular CSS commands to do
    exact placement of text in the window of the
    browser
  • This is as close as XML gets (today) to being a
    print stream
  • Fonts are still subject to user override

45
Pros And Cons Of Translation
  • Pros
  • Author has very good control over the
    presentation of text
  • Cons
  • Much of the value of a tagged language is lost
  • Portrait print pages still dont fit on landscape
    browser windows
  • May not work with all browsers
  • Fonts can still be overridden
