Almost there with CUPS

[pgcudahy]

Hey guys, after a few hours of set-up I'm agonizingly close to having my tinycore box set up as a network print server. I followed the instructions for setting up cups1311 and the followed this posthttp://forum.tinycorelinux.net/index.php?topic=3559.0 (http://forum.tinycorelinux.net/index.php?topic=3559.0) to set up printer sharing. I can print from the tinycore box, but when I send a print job from my mac it just sits in the job que and does nothing with the state of "stopped". I can even pull up the cups admin webpage from my mac and print off a test page from there, but any jobs sent from my mac just linger in the que. Any ideas on how to troubleshoot this?

hi

I cheated and the wiki uses cups1311 to save doing some root things.

I also do not have any other computers but suggest you look, as they are your current packages, to see if you can add a networked computer, while my wiki added a local printer.

Forgive me if you already understood this.

2) I have no way of testing, but you may be better off, removing cups1311 and going for "normal" cups and add a networked printer?

[pgcudahy]

Thanks aus9, maybe it would be easier to try with the regular cups rather that try and mess with the rootless version. However, I don't think that authorization is the issue. I figured out how to get better debug messages from cups and it seems like the interesting part of the log is

I checked and pdftops is there in /usr/local/lib/cups/filter (as a symlink to /tmp/tcloop/cups1311/usr/local/lib/cups/filter/pdftops) yet cups sends off an error that "Unable to execute pdftops program: No such file or directory" Any thoughts?

[tinypoodle]

you could

Code: [Select]

/usr/local/lib/cups/filter/pdftops yourtestfile.pdf
and see what happens...  

I'd rather interprete output as pdftops sending off error of not finding file or dir (possibly pdf input file)

[pgcudahy]

Good thought. You're right, running pdftops on a test file results in it happily crunching away on it. Maybe the issue is in the next few lines when pstops complains about an empty print file. Cause when I think about it, the mac should be sending a postscript file, not a pdf.

[pgcudahy]

Turns out you were right tinypoodle. I installed poppler which has pdftops and now it's working. I think what was happening was that pdftops wasn't working and then passing off an empty file to pstops. Thanks for the help
