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 01 and 02 of this document 33 Only minor revisions. 35 Abstract 37 Certain text formats, for example Postscript (extension .ps, Mime-type 38 application/postscript) and Adobe Acrobat (extension .pdf, Mime-type 39 application/pdf) specify exactly the page layout of the printed 40 document. The commonly used paper format is different in America and the 41 rest of the world. America uses the 'Letter' format, while the rest of 42 the world mostly uses the ISO-standard 'A4' format. This means that 43 documents formatted on one continent may not be easily printable on 44 another continent. This memo gives advice on how to produce documents 45 which are equally well printable with the Letter and the A4 formats. By 46 using the advice in this document, you can put up a document on the 47 Internet, which recipients can print without problem both in and outside 48 America. 50 A very short summary of the advice in this document: If you are using 51 U.S. Letter paper format, ensure that both the left and right margins 52 are at least 21 mm (0.82 inches). If you are using A4 paper format, 53 ensure that both the top and bottom margins are at least 33 mm (1.30 54 inches). 56 Table of contents 58 1. Introduction 59 2.

Introduction 67 Certain text formats, for example application/postscript (extension .ps) 68 and Adobe Acrobat (extension .pdf) specify exactly the page layout of 69 the printed document. The commonly used paper format is different in 70 America and the rest of the world. America uses the "Letter" format, 71 while the rest of the world uses the "A4" format. 73 The American Letter format is 8.5 x 11 inches (216 x 279 mm) while the 74 ISO standardised A4 format is 210 x 297 mm (8.27 x 11.69 inches). The 75 Letter format is thus 5 mm (0.19 inches) wider, while the A4 format is 76 19 mm (0.75 inches) taller. 78 This means that documents formatted on one continent may not be 79 printable on another continent. It is oboviously desirable that 80 documents put up on the Internet are printable on all continents. This 81 paper gives advice on how to achieve this. 83 This memo is not intended for HTML documents, but the advice may be of 84 value also of HTML developers in case they are using fixed-size graphics 85 and fixed WIDTH sizes of objects in HTML documents. 87 2. Two methods for printing on different paper formats 89 2.1 Method 1: Use wider margins 91 Paper format 92 you use when 93 converting 94 the document Suggested minimal margins 95 to Postscript Paper 96 or Acrobat orien- Suggested change Left Right Top Bot- 97 format tation of margins tom 98 ------------ ----------- ----------------- ----- ----- ----- ----- 99 A4 Portrait Add 18 mm (0.8 15 mm 15 mm 33 mm 33 mm 100 (upright, inches) to the top 0.59" 0.59" 1.38" 1.38" 101 vertical) of page and bottom 102 of page margins 104 A4 Landscape Add 18 mm (0.8 33 mm 33 mm 15 mm 15 mm 105 (lying, inches) to the 1.38" 1.38" 0.59" 0.59" 106 horizontal) left and right 107 margins 109 Letter Portrait Add 6 mm (0.2 21 mm 21 mm 15 mm 15 mm 110 (upright, inches) to the 0.82" 0.82" 0.59" 0.59" 111 vertical) left and right 112 margins 114 Letter Landscape Add 6 mm (0.2 15 mm 15 mm 21 mm 21 mm 115 (lying, inches) mm to the 0.59" 0.59" 0.82" 0.82" 116 horizontal) top of page and 117 bottom of page 118 margins 120 The reason why you have to add 18 respectively 6 mm to both the top and 121 the bottom margin is that you do not know what kind of printer the 122 recipient uses, and different printers feed paper in different ways, 123 requiring the margin to be added either at the top or the bottom of the 124 paper. 126 Note: Ensure that also headers, footers and page numbers are within the 127 suggested minimal margins. Many word processors put headers, footers and 128 page numbers outside the specified text margins. 130 2.2 Method 2: Print with reduced size 132 This is a method useful for the recipient of a document with the wrong 133 paper size: The recipient sets the printer to print with reduced size. 134 When the sender produces the Acrobat or Postscript files, the sender 135 should "print" with 100 % size, but when the recipient prints the 136 Acrobat or Postscript files, and if the program for printing Acrobat or 137 Postscript files allows this, the recipient should print the document 138 with 94 % or less of full size. Many programs for printing Postscript 139 files do not allow this. In that case, the recipient can convert a 140 Postscript document to Acrobat format and then print it with the Acrobat 141 printing program. This requires, however, that the recipient has the 142 Acrobat Distiller program, which is not freeware. Some versions of the 143 freeware ghostscript can also convert to Adobe Acrobat format. The user 144 may also have to specify the paper size as the actual paper size loaded 145 in the printer, not the paper size specified when the document was 146 converted to Acrobat or Postscript format. 148 It is also possible to edit the Postscript file, and add a scale command 149 to it, before sending it to the printer. 151 Method 2 can be more difficult for the recipient, who has to manage 152 these settings himself. However, manufacturers of printing software may 153 in the future make method 2 easier by making this service automatic, 154 perhaps controlled by a "shrink to fit paper size" checkbox in the 155 printing window and a "default shrink to fit paper size" preference 156 setting. 158 2.3 Method 3: Buy paper in the A4 size 160 People in America who often need to print European document might choose 161 to buy paper in the A4 size. It is available in the U.S. from many large 162 paper distribution company, and almost all laserprinters support it. 164 3.
