For best results you will want to enable two sided printing (left and right hand side papers have different margins) at LaTeX level:
Title
#####
< <class: book!a4paper,12pt!portuges!Zita Lopes, LIP>>
< <linespace: 1.5!!\medskipamount>>
< <author: Zita Maria Oliveira Lopes Kellomäki>>
< <moretexpreamble:
\setlength{\evensidemargin}{15pt}
\setlength{\oddsidemargin}{45pt}
\hyphenation{GEANT Sam-po Kel-lo-mä-ki com-ple-men-tam e-xac-ta}
>>
You can print A5 booklets with the following receipe:
pd2tex file.pd pdftops tex/file.pdf psbook tex/file.ps tex/file-book.ps # omit -s for best result mpage -o -2 -j1%2 tex/file-book.ps # odd sheets # HP4100: rotate output by 180 degrees and put in input tray with image up (p. 1) mpage -o -2 -j2%2 tex/file-book.ps # even sheets # invert order of output, fold, and staple in middle
Provided that you did not screw up with mental gymnastics regarding geometry and transformations that relate to inserting the papers in the right orientation for the second printing pass, you should now have a stack of double side printed A4s that you can fold in middle and staple in the center to make your booklet. Folding will often produce uneven right edge of papers. The best fix is to simply use a good guillotine to even it out.
