1. Problematic little quotes Not acceptable the quote marks crash into the p or are too close to the word little This is caused by a bug in the PDF level 1 2 output of Ghostscript versions 7 00 7 05 as well as the 7 20 7 21 developer versions It has been fixed in releases dated after 2002 07 31 A work around is to use only PDF level 1 3 or higher as supported by more recent versions of Ghostscript output via the use of dCompatibilityLevel 1 3 when making PDF using Ghostscript Do not ignore this problem because it looks like a small defect There are other manifestations that are much more severe 5 11 The Picture and Lasy Fonts Test ET X has a special set of fonts used to construct simple pictures and a set of fonts the lasy fonts with rarely used symbols The original release of the type 1 versions BlueSky of these fonts contained some normally harmless extraneous information within the font files However Acrobat Readers in the 5 0 series are intolerant of this extra information and will generate a font error when printing to a PostScript printer There may or may not be noticeable problems in the resulting print Not acceptable Acrobat Reader 5 x generates a font error when printing to a postscript printer This error message may not a reliable indicator of whether or not the user s ATEX picture and lasy fonts have the offending data as an error message may not be triggered unless the document us2. While most PostScript parser reader applications will expect BoundingBox 0 0 595 842 Normally this is of no consequence One minor notable issue is that the Unix gv application uses the BoundingBox to determine the paper size if no PostScript paper size commands are present and it will not recognize a PS file as wanting A4 if it sees 596 instead of 595 The workaround is to use A4size 594 99bp 841 99bp instead of 210mm 297mm for A4 measurements Those outside the US are probably laughing at this point pun intended but it should be pointed out that this is a standards issue not a units issue Ghostscript versions prior to 7 05 have a very similar problem if they are compiled with the DA4 option A4 PDF pages produced with ps2pdf will be very slightly scaled down about 1 With all this in mind a good first set of dvips config ps paper size definitions for US letter paper users might look like lettersize 8 5in 11lin PaperSize Letter letter 8 5in 11lin DocumentPaperSizes Letter BeginPaperSize Letter letter EndPaperSize A4size 594 99bp 841 99bp PaperSize A4 6 APPLICATION VERSION AND CONFIGURATION INFORMATION 15 a4 594 99bp 841 99bp DocumentPaperSizes al BeginPaperSize al a4 EndPaperSize A4 users would want to move the A4size block to the first position so that it will be the default Type 1 Font Configuration Most TEX systems al
