Re: [K12OSN] Laser Printer super-slow?

Could it be a problem with PDFv3? I had an older printer that didn't support PDFv3, and each time I would try to print, it would spend a long time "thinking about it", and maybe part of the document would print, and then the job would fail.

If you're using Adobe Reader to print the PDF, click on the Advanced button at the lower left quarter of the Print menu. The Advanced Print Setup window will pop up. If Language is set to "Language Level 3", try changing it to "Language Level 2".

Something to try, anyway.

So a text file prints quickly but a complicated pdf fails.

So some things to look at are: what is the server using resource wise just before the failure? sysstat is a tool to monitor system usage. It can be tweaked in /etc/cron.d to run more frequently than every 10 minutes.

I would suggest testing with a less complicated (i.e. shorter) pdf. Make a page or two in openoffice or extract a few pages from the 200 page monster and try again. pdftools are a commandline option as well as just printing a few pages. 17+ hours sounds like a memory shortage to me. Sysstat will show disk usage in terms of swapfile activity.

Oh. The tool to view graphs of sysstat data is called sar. Uses java and outputs really useful graphs. excellent tool!

    A single page of text from notepad prints fairly quickly. Â The
    seems to focus around PDFs I believe as those are the only larger
    documents I've printed.

    I sent a 200 page PDF (with some images, total size of the PDF 7 MB)
    and ran top. Â What I saw, over the *17 hours* it took to print 100
    pages before it just crashed, was the cpu on the thin client not going
    over 2% and no swap being touched. Â It looked like it was printing a
    page every 10 minutes or so, and then towards the last few pages the
    CPU usage went up to 99% and then back down to zero once it was
    finished. Â The process was the jetdirect one I believe (don't
    have the
    file in front of me).

    So I'm not quite sure what the issue is. Â The thin client is a
    4 2.6 Ghz machine with a gig of RAM.
