okular: cups and lpd mismatch?

[uzsolt]

Hi all!

I'm using the standard lpd() to print.
While the print/cups-client combined into print/cups can't use the standard lpd only from commandline.
When I want to print from graphics/okular it prints into stdout (or stderr):

lpr-cups: Bad file descriptor

I think it calls /usr/local/bin/lpr and it causes an error because the cupsd not running. My PATH is:

/sbin/:/usr/sbin/:/usr/bin:/bin:/usr/local/libexec/ccache:/home/zsolt/bin:/usr/local/bin:/sbin/:/usr/sbin/:/home/zsolt/bin:/usr/local/bin

Note that the /usr/local/bin (directory of cups's lpr) is the last.

How can I print from okular?

vigole You misunderstood me. I don't use cupsd, I'm using LPD.

I don't know about Qt based applications but gtk3 removed LPD support in the print dialogs. My work around is to print to a file (*ps vs *pdf). If you have a pdf you can convert to postscript pdf2ps, print/ghostscript9-base, or pdftops, graphics/poppler-utils The latter command renders better for me. Another option is to open the pdf in something like graphics/xpdf and use that print dialog.

Most current PostScript printers actually understand PDF natively. In theory, anyway.

Does okular offer any configuration of the command it uses to print, like graphics/xpdf does?

 

[uzsolt]

wblock@ I think you can't set command in Okular, see core/fileprinter.cpp.

Edit: I've opened an Okular-bug report about it.

And do you print from command line (using /usr/bin/lpr generated.ps)? I don't want this because my girlfriend uses graphics/okular and she doesn't like CLI

Yes, I print from the command line or non-gtk3 applications (Firefox-esr). The lack of direct printing to LPD is an upsteam decision for gtk3 that I found on a Redhat/Fedora mailing list.
The grandfather of okular/evince is print/gv, it will open pdfs/postscript files and has a "print" button.
I did a quick web search and found this. Not sure if the workaround is still an option. If not then you may have to use cups to keep peace.

It seems it's the time when added the lpr-checking what I linked above.

I think I've two choices as you wrote: an ugly workaround (re-link /usr/local/bin/lpr-cups to /usr/bin/lpr) or use print/cups on my girlfriend's machine.
