cups-devl supportForum: Apps Topic: cups-devl support started by: jpeters Posted by jpeters on June 17 2006,23:11
I'm attempting to configure/install a printer driver, and get an error message about not being able to find cups.h,and thus "no cups-devl support". I have cups loaded, up and running. Any solutions? (note: I finally got libusb installed, so this is the latest barrier). I loaded cups from MyDsl, in addition to apt-get; also ran updates. ThanksEdit: My girlfriend just read my post, and informed me that support for an 'h' cup is a little too much to ask for. Posted by ZoOp on June 18 2006,09:10
I tried to get cups loaded in localhost: I opened firefox and type< http://localhost:631 > I intended to help you with this advice, but got surprisingly this error message: server not available... 2nd possibility: try to configure your printer with apsfilter (e.g. the printer utility in the DSL menu), and look at < http://www.linuxprinting.org/ > in order to check out the right driver for your printer. Sorry not to be able to help more. yours z Posted by jpeters on June 18 2006,21:54
Hi ZoOp,The link worked for me, although I've noticed the server goes down fairly often. Cups and Apsfilter don't work for my printer (a HP 940C deskjet plugged into my USB port on a Dell laptop) because no device shows up on any path (/dev/usb/lp0, etc.....). Thus, I've attempted to build a driver, HPLIP, hoping that the printerdevice will show up on a USB port. Cups is installed (although it can't load a printer driver due to no printer device being found). When attempting to configure HPLIP, I get the error about not finding CUPS support. Perhaps I need to export a correct path?? I have no idea whether a device will show up even if I do manage to configure and install the driver. I was hoping LIBUSB would take care of the problem, but it did not. The printer works when I load Knoppix live CD. Maybe there's a way to copy some info over to DSL.

Hi jepeters, please correct me if I understand you wrong, but apsfilter doesn't show you a device; it shows you only paths that are numbered, and you have to enter a number in order for apsfilter to take your input into account and set up the corresponding path (=which corresponds to the number you entered). These paths are various, generally one or two for lpt and one or two for usb. I don't think that you can copy what you want from knoppix to dsl because of dependencies. yours z Posted by jpeters on June 19 2006,03:20
After choosing the number (eg., "1" for parallel/usb), it asks for the path (eg., /dev/usb/lp0). When testing, I get an error message that it can't find a device on that (or any other) path; same problem occurs using CUPS. I think you're right regarding dependencies. I'm hoping to find the magic library or driver that makes it work (just for the learning experience; I could always boot up Knoppix and print out a file). Posted by ZoOp on June 19 2006,07:38
Hi, strange strange... another question in order to invalide another hypothesis: do you enter the "install"-command (the big I) in apsfilter after choosing the path and before printing a test page? I know from my own experience that it is always something that one can easily forget. Otherwise, we have to assume that there is a problem with the usb port or your machine or the usb cable, but probably not with your usb-printer, which should work fine with apsfilter or cups, and which should work fine with DSL, too, since DSL install usb-printers well, as I experienced with other usb-printers running the pxlmono. Do you have the possibility to plug a lpt cable in your printer in order to configure it on /dev/lpt/lp0? yours z Posted by jpeters on June 19 2006,09:46
I think you can test before installing, but in any event, it can't find a device either way. It DID work with a parallel port cable I got from another computer using the GIMP driver, and I was able to print a test page both from apsfilter and CUPS. I wasn't able to print from any apps in either case, as the printer setup didn't include the loaded driver (I tried OO and Beaver).

strange strange strange...in order to control the possible issue with your usb port, I would plug a usb-stick (once at boot and once when DSL is running) in order to check if dsl recognizes it and mount/unmount it without problem. If yes, then it is not your machine, and then I have no other solution... It's really surprising to me, because I'm using a samsung usb-printer with an hp driver and apsfilter, and everything is fine. I checked also the linuxprint.org and forums for solution, but only can find that your printer should work with linux (lots of users saying it works fine, etc.). So, we have to bring it to work, too. yours z Posted by jpeters on June 19 2006,14:46
The USB ports work fine for attaching memory sticks, external hard drives, etc. Any clue why apps didn't print even after cups was loaded and printing out test pages successfully on the parallel port? Posted by ZoOp on June 19 2006,14:52
... very sorry not to be able to help you more than that.all my apps print fine (on lp and not lpr or lp0), xpdf, ooo, beaver, etc. in parallel or usb mode, and I have a 10 years old machine. My opinion is still that you have a hardware problem, but where if not the usb port??? yours z Posted by jpeters on June 19 2006,15:25
Except that it works using Knoppix live CD, suggesting it's a software problem. Also, the same problem occurs on two computers (Latitude and Inspirion). Thanks for your help and ideas. Regarding not being able to print apps, I just checked out the cups manual noting that you print from the command line and not from inside the app. |
