    After a lot of time using xsane with the options
    color, 150 dots and using gigantic 4 MB/page,
    I choose color, 100 dots and the result is about
    half the weight, worth the change in most cases.
    xsane uses pdf version 1.4

    Now the mistery: in the current LibreOffice I made
    a page and export it to a pdf version 1.5
    The page contains text, a table, and a pair of png
    Using evince after, to view and print, I encounter
    the problem that I can see the page good in screen
    but it does not print the final of the page with
    one table and a png. So what's up? An evince problem
    or a malformed pdf?

    TIA

    Or maybe a problem with the print pipeline or the printer. I have had
    quite a number of cases where printing choked at a specific page in a
    document; sometimes it then worked if I printed only starting at that
    page. My guess was that the printer ran out of memory, but I never investigated it in depth.

    In any case, for your case the question is in what format the page is
    sent to the printer; in PDF, or converted by the print pipeline to
    some other format. If the latter, you could investigate the converted
    format (e.g., if it's Postscript, do Postscript viewers display it?).

    You could also try to convert the document to another format with
    various tools, and look if the result displays with a viewer and
    prints with the printer.

    The ones I might try:

    mutool trace

    ghostscript (so you can look for stack dumps or something)

    While there are other tools, not all the tools are "expressive"
    enough. And hide how things are going.

    It's probably just a broken print pipeline, if Evince shows
    a perfectly good picture on the screen.

    Thank you both.

    So, if probably the printer pipe is broken I should try a good old
    reset. Correct?

    I don't know printing well enough, to comment on that.
    About all I can suggest, is turning on as much logging
    as you can manage, so there is an evidence trail.

    I was thinking about permanent breakage (like a converter not being
    able to grok the PDF), but sure, it's also possible that you have some temporary problem. But the typical print-manager stuff (e.g., CUPS) is
    written to keep state over reboots, so it's a little more involved to
    get it unstuck.

    Maybe there is no that kind of breakage.
    I set the printer to 1200HQ and the pdf only is printed on 600dpi
    Problems that something appairs and something not maybe for this

    Thank you

    O.P. could also load atril and try printing the PDF file with that...

    (I have pretty good success printing PDF files iwth Atril)

    I stopped using Evince a while back since I use Mate on everything, and
    Evince seems a bit bloated to me.

    print a test page with CUPS maybe

    sounds more like a scaling issue. Print is by millimeters/inches, and
    not by dot pitch. The PDF is scaled in millimeters/inches as well, and
    the viewer will scale the print accordingly. Did you look at 'Print
    Preview' to see what it was trying to do? Just curious. Print Preview
    should match what the printer is doing. If not, maybe you need to check
    your CUPS drivers to see that they're the right ones. Print some test
    pages and other documents with other programs, etc..
