A simple but effective method for those of us with "dumb" printers is to open the document (after it's been processed into PostScript by groff -- see <a href="using.html#USING_INVOKING">How to invoke groff with mom</a>) in <strong>gv</strong> (ghostview), click the "odd pages" icon, then click "Print Marked". After printing is complete, rearrange the sheets appropriately, put them back in your printer, and have <strong>gv</strong> print the "even pages". If you prefer to work from the command line, check out the man pages for <strong>pstops</strong> and <strong>psbook</strong>. There are other programs out there as well to help with two-sided printing. <p> <a name="RECTOVERSO_LIST"> <h3><u>Recto/verso macros list</u></h3> </a> <ul> <li><a href="#RECTO_VERSO">RECTO_VERSO</a> <li><a href="#SWITCH_HDRFTR">SWITCH_HEADERS (also FOOTERS)</a> </ul> <p> <hr> <!---RECTO_VERSO---> <a name="RECTO_VERSO"> <h3><u>Recto/verso printing</u></h3> </a> Macro: <strong>RECTO_VERSO</strong> <p> If you want <strong>mom</strong> to set up alternating pages for recto/verso printing, simply invoke <strong>RECTO_VERSO</strong> with no argument. <p> <strong>NOTE:</strong> <br> Recto/verso always switches the left and right parts of <a href="definitions.html#TERMS_HEADER">headers</a> or <a href="definitions.html#TERMS_FOOTER">footers</a> on odd/even pages. However, it only switches the left and right margins if the margins aren't equal. Consequently, it is your responsibility to set the appropriate differing left and right margins with <a href="typesetting.html#L_MARGIN">L_MARGIN</a> and <a href="typesetting.html#R_MARGIN">R_MARGIN</a> (prior to <a href="docprocessing.html#START">START</a>) or with <a href="docprocessing.html#DOC_LEFT_MARGIN">DOC_LEFT_MARGIN</a> and <a href="docprocessing.html#DOC_RIGHT_MARGIN">DOC_RIGHT_MARGIN</a> (before or after <strong>START</strong>). <p> Equally, recto/verso only switches the page number position if page numbers aren't centred, which means you have to set the page number position with <a href="headfootpage.html#PAGENUM_POS">PAGENUM_POS</a> (before or after <strong>START</strong>). <p> <!---SWITCH_HDRFTR---> <hr width="66%" align="left"> <a name="SWITCH_HDRFTR"> <h3><u>Switch header left part/right part</u></h3> </a> Macro: <strong>SWITCH_HEADERS</strong> <p> <strong>SWITCH_HEADERS</strong> switches the location of the header left string (by default, the author) and the header right string (by default, the document title). If you don't like <strong>mom</strong>'s default placement of author and title, use <strong>SWITCH_HEADERS</strong> to reverse it. <p> <strong>SWITCH_HEADERS</strong> can also be useful in conjunction with <a href="#RECTO_VERSO">RECTO_VERSO</a>. The assumption of <strong>RECTO_VERSO</strong> is that the first page of a document (recto/odd) represents the norm for header-left and header-right, meaning that the second (and all subsequent even) page(s) of the document exchange header-left and header-right. <p> If <strong>mom</strong>'s behaviour in this matter is not what you want, simply invoke <strong>SWITCH_HEADERS</strong> on the first page of your recto/verso document to reverse her default treatment of header parts. The remainder of your document (with respect to headers) will come out as you want. <p> <strong>NOTE:</strong> Replace <strong>_HEADERS</strong>, above, with <strong>_FOOTERS</strong> if your document uses footers. <p> <hr> <!=====================================================================> <a name="COLLATE_INTRO"> <h2><u>Introduction to collating</u></h2> </a> The macro <strong>COLLATE</strong> lets you join documents together. Primarily, it's a convenience for printing long documents that comprise several chapters, although it could be used for any document type (except <strong>LETTER</strong>). <p> Personally, I prefer to keep chapters in separate files and print them out as needed. However, that means keeping track of the correct starting page number for each chapter, a problem circumvented by the use of <strong>COLLATE</strong>. <p> When collating chapters, you need only put <code>.COLLATE</code> at the end of a chapter, follow it with any <a href="docprocessing.html#REFERENCE_MACROS">reference macros</a> needed for the new chapter, e.g. <a href="docprocessing.html#CHAPTER">CHAPTER</a> or <a href="docprocessing.html#CHAPTER_STRING">CHAPTER_STRING</a> (have a look at the <a href="#CHAPTER_NOTE">Special Note on CHAPTER</a>) make any pertinent style changes to the document (unlikely, but possible), and re-invoke the <a href="docprocessing.html#START">START</a> macro. Your new chapter will begin on a fresh page and behave as expected. <p> <strong>COLLATE</strong> assumes you are collating documents/files with similar type-style parameters hence there's no need for <strong>PRINTSTYLE</strong> to appear after <strong>COLLATE</strong>, although if you're collating documents that were created as separate files, chances are the <strong>PRINTSTYLE</strong>'s already there. <p> <a name="CAUTION"></a> <strong><u>Two words of caution:</u></strong> <ol> <li>Do not collate documents of differing <strong>PRINTSTYLES</strong> (i.e. don't try to collate a TYPESET document and TYPEWRITE document). <li>Use <strong>DOC_FAMILY</strong> instead of <strong>FAMILY</strong> if, for some reason, you want to change the family of all the document elements after <strong>COLLATE</strong>. <strong>FAMILY</strong>, by itself, will change the family of paragraph text only. </ol> <p> <!---COLLATE---> <hr width="66%" align="left"> <a name="COLLATE"> <h3><u>Collate document files</u></h3> </a> Macro: <strong>COLLATE</strong> <p> The most basic (and most likely) collating situation looks like this: <p> <pre> .COLLATE .CHAPTER 17 .START </pre> A slightly more complex version of the same thing, for chapters that require their own titles, looks like this: <p> <pre> .COLLATE .CHAPTER_TITLE "Geek Fatigue: Symptoms and Causes" .START </pre> <strong>NOTE:</strong> See the <a href="#CAUTION">two words of caution</a>, above. <p> <hr> <a href="cover.html#TOP">Next</a> <a href="headfootpage.html#TOP">Prev</a> <a href="#TOP">Top</a> <a href="toc.html">Back to Table of Contents</a> </body> </html>
