I've a CanonS100SP USB printer and I've added it through http://localhost:###. It worked when I printed test page. However when I tried to print some real stuff, like pdf or web pages, I got this error message:

A print error occurred. Error message received from system:

Moreover, there is no cups printing option in firefox. The only one available is "PostScript/default". why?

Somebody help me.

Printing in linux, could it be more hard?

What is your printer name in cups ?

Your programs are trying to print to an lpr printer. You need to link lpr requests to cups. Search the posts on how to do that.

As for firefox, the easiest solution is in this link: www.CS.umd.edu/faq/cups.html

You can download gtklp (slack9.1 version) from: www.linuxpackages.net

However, note that the location of the gtklp file is slighlty different from the example location.

If you click on "properties" from the print dialog in Firefox you will see it is using lpr. So you need to adjust the lpr to point to lpr-cups. As north49er said do a search, this has been covered at least twice in the last 2 weeks.

I set up my printer according to advice at:
http://www.linuxquestions.org/questi...light=Printing
and have had no problems. Prints well from firefox too.
I don't know if the fact that my printer is a hp makes any difference; suspect the it doesn't.

My advice is this:

1) Use pkgtool to remove lprng
2) Re-install CUPS from the installation Disk

You should be working fine. /usr/bin/lpr will now be a symbollic link to /usr/bin/lpr-cups .

Not sure if this is exactly the answer for your question, but there's a wierdness in Slackware that if you install both Cups AND lprng, things will conflict. My suggestion is to uninstall them both. Then decide which one you want and install just that one. Maybe this will help?

I don't know if it will cause problems in the future, but I just un-linked lpr from lprng and then re-linked it to lpr-cups and firefox seems to print just fine. I didn't uninstall anything (all though I'll be uninstalling lpr in just a few as I don't need it) and I didn't re-install cups.
