I'm pretty sure it's a last name (https://en.wikipedia.org/wiki/Spanish_naming_customs), but anyway, what's happening is that some characters are trimmed from the middle of each path section.

Oh I see, I thought it was the other way. I just tested adding some troublesome titles after unchecking that "Convert non-English..." option, but this didn't help. Tomorrow i'll fiddle some more with it, trying command line too

Calibre's save path code works by first computing the total path length then comparing that to the maximum allowed, which is system dependent. If the total is longer than the maximum then each segment of the path is shortened (from the middle) by enough to make the path fit.

You can control this process using a template that uses the template shorten() function for each name segment. The function lets you decide how many characters to remove from each segment, removing the randomness of the default process. If done correctly then the total length is guaranteed to be less than the maximum.

Just to clarify, when I say "what's happening", it's just an explanation of why the path name is not the full author/title, which is fine and expected as per chaley's explanation. I don't mean that is the problem. It still puzzles me that you get different lengths, but that may be just my ignorance when using the template in the plugin's code. The problem seems to be that Prince itself (or the command-line interpreter that runs Prince) chokes on the path that's being passed. It could be that I'm not ensuring it's short enough, or it could be that Prince requires it shorter than the system limit, or it could be something else.

Hi Jellby,

For most conversions, I'm using this CSS:

PHP Code:

body  {background-color:transparent !important;}
@font-face {font-family: serif;  src: local("ChareInk6")}

@page {
  size: 17cm 32cm;
  margin: 5mm 3mm 5mm 3mm !important;
    @top-left {
    font-size: 50%;
    font-style: italic;
    border-bottom: solid thin black;
    margin-bottom: 1mm;
    content: string(booktitle);
    
  }
  @top-center {
    font-size: 50%;
    font-style: italic;
    border-bottom: solid thin black;
    margin-bottom: 1mm;
    content: string(chaptertitle);
  }
  @top-right {
    font-size: 50%;
    border-bottom: solid thin black;
    margin-bottom: 1mm;
    content: counter(page) "/" counter(pages);
  }
}

@page:first {
  margin: 1mm 1mm 1mm 1mm;

  @top-left {
    border-width: 0;
    margin: 0;
    content: normal;
  }
  @top-center {
    border-width: 0;
    margin: 0;
    content: normal;
  }
  @top-right {
    border-width: 0;
    margin: 0;
    content: normal;
  }
}

body {
  font-size: 15pt;
  font-family: "ChareInk6";  
  text-align: justify;
  prince-image-resolution: 166dpi;
  hyphens: auto;
  string-set: booktitle "@{@{title}@}@"
  string-set: author "@{@{author}@}@"
 } 


Now I noticed that, on books with large covers, the cover image exceeds the printing area on the converted PDF's first page.

Is there some CSS styling I can apply to get the cover to fit the page size (17cm x 32cm, in most cases)?

[Jellby]

I don't think there's a general solution. It depends on how the books is coded (and also Prince's behaviour has changed between versions in the past).

In many of my books I have something like:

/* specific code for the cover image */
@page cover {
  size: 600px 800px; /* hard-coded cover image size */
  margin: 0 -100px;  /* make virtual page width 800px */
}

body.cover {
  page: cover;
}

But this relies on:
* The cover image being in a <body class="cover"> tag.
* The cover image being 600x800 px exactly.
* The cover image being coded to use the full page.

At least at some point this worked fine for me.

Yes, that's what I thought. Fortunately, I've realized this happens only with a few titles, so it's just a matter of tweaking the cover styling in Editor to make it fit. Thanks.
