Internet-Drafts are working 12 documents of the Internet Engineering Task Force (IETF), its areas, and 13 its working groups. Note that other groups may also distribute working 14 documents as Internet-Drafts. 16 Internet-Drafts are draft documents valid for a maximum of six months 17 and may be updated, replaced, or obsoleted by other documents at any 18 time. It is inappropriate to use Internet-Drafts as reference material 19 or to cite them other than as ``work in progress.'' 21 To learn the current status of any Internet-Draft, please check the 22 ``1id-abstracts.txt'' listing contained in the Internet-Drafts Shadow 23 Directories on ftp.is.co.za (Africa), nic.nordu.net (Europe), 24 munnari.oz.au (Pacific Rim), ds.internic.net (US East Coast), or 25 ftp.isi.edu (US West Coast). 27 This memo provides information for the Internet community. This memo 28 does not specify an Internet standard of any kind. Distribution of this 29 memo is unlimited. 31 Differences between version 00 and 01 of this document 33 The second paragraph in the abstract is new, and text about "shrink to 34 fit" facilities has been added at the end of chapter 2.2. A note about 35 HTML has been added to chapter 1, a note about headers and footers has 36 been added at the end of chapter 2.1. 38 Abstract 40 Certain text formats, for example Postscript (extension .ps) and Adobe 41 Acrobat (extension .pdf) specify exactly the page layout of the printed 42 document. The commonly used paper format is different in America and the 43 rest of the world. America uses the "Letter" format, while the rest of 44 the world uses the "A4" format This means that documents formatted on 45 one continent may not be easily printable on another continent. This 46 memo gives advice on how to produce documents which are equally well 47 printable with the Letter and the A4 formats. By using the advice in 48 this document, you can put up a document on the Internet, which 49 recipients can print without problem both in and outside America. 51 A very short summary of the advice in this document: If you are using 52 U.S. Letter paper format, ensure that both the left and right margins 53 are at least 21 mm (0.82 inches). If you are using A4 paper format, 54 ensure that both the top and bottom margins are at least 35 mm (1.38 55 inches). 57 Table of contents 59 1. Introduction 60 2.

Introduction 68 Certain text formats, for example application/postscript (extension .ps) 69 and Adobe Acrobat (extension .pdf) specify exactly the page layout of 70 the printed document. The commonly used paper format is different in 71 America and the rest of the world. America uses the "Letter" format, 72 while the rest of the world uses the "A4" format. 74 The American Letter format is 8.5 x 11 inches (215 x 278 mm) while the 75 ISO standardised A4 format is 210 x 297 mm (8.27 x 11.69 inches). The 76 Letter format is thus 5 mm (0.19 inches) wider, while the A4 format is 77 19 mm (0.75 inches) taller. 79 This means that documents formatted on one continent may not be 80 printable on another continent. It is oboviously desirable that 81 documents put up on the Internet are printable on all continents. This 82 paper gives advice on how to achieve this. 84 This memo is not intended for HTML documents, but the advice may be of 85 value also of HTML developers in case they are using fixed-size graphics 86 and fixed WIDTH sizes of objects in HTML documents. 88 2. Two methods for printing on different paper formats 90 2.1 Method 1: Use wider margins 92 Paper format 93 you use when 94 converting 95 the document Suggested minimal margins 96 to Postscript Paper 97 or Acrobat orien- Suggested change Left Right Top Bot- 98 format tation of margins tom 99 ----------- ----------- ----------------- ----- ----- ----- ----- 100 A4 Portrait Add 20 mm (0.8 15 mm 15 mm 35 mm 35 mm 101 (upright, inches) to the top 0.59" 0.59" 1.38" 1.38" 102 horizontal) of page and bottom 103 of page margins 105 A4 Landscape Add 20 mm (0.8 35 mm 35 mm 15 mm 15 mm 106 (lying, inches) to the 1.38" 1.38" 0.59" 0.59" 107 vertical) left and right 108 margins 110 Letter Portrait Add 6 mm (0.2 21 mm 21 mm 15 mm 15 mm 111 (upright, inches) to the 0.82" 0.82" 0.59" 0.59" 112 horizontal) left and right 113 margins 115 Letter Landscape Add 6 mm (0.2 15 mm 15 mm 21 mm 21 mm 116 (lying, inches) mm to the 0.59" 0.59" 0.82" 0.82" 117 vertical) top of page and 118 bottom of page 119 margins 121 The reason why you have to add 20 respectively 6 mm to both the top and 122 the bottom margin is that you do not know what kind of printer the 123 recipient uses, and different printers feed paper in different ways, 124 requiring the margin to be added either at the top or the bottom of the 125 paper. 127 Note: Ensure that also headers, footers and page numbers are within the 128 suggested minimal margins. Many word processors put headers, footers and 129 page numbers outside the specified text margins. 131 2.2 Method 2: Print with reduced size 133 This is a method useful for the recipient of a document with the wrong 134 paper size: The recipient sets the printer to print with reduced size. 135 When the sender produces the Acrobat or Postscript files, the sender 136 should "print" with 100 % size, but when the recipient prints the 137 Acrobat or Postscript files, and if the program for printing Acrobat or 138 Postscript files allows this, the recipient should print the document 139 with 92 % or less of full size. Many programs for printing Postscript 140 files do not allow this. In that case, the recipient can convert a 141 Postscript document to Acrobat format and then print it with the Acrobat 142 printing program. This requires, however, that the recipient has the 143 Acrobat Distiller program, which is not freeware. The user may also have 144 to specify the paper size as the actual paper size loaded in the 145 printer, not the paper size specified when the document was converted to 146 Acrobat or Postscript format. 148 Method 2 can be more difficult for the recipient, who has to manage 149 these settings himself. However, manufacturers of printing software may 150 in the future make method 2 easier by making this service automatic, 151 perhaps controlled by a "shrink to fit paper size" checkbox in the 152 printing window and a "default shrink to fit paper size" preference 153 setting. 155 3.
