 Posted: Mon Feb 19, 2007 10:33 pm Post subject: cups doesn't recognize USB printer [SOLVED] |
 |
|
Hello,
I'm trying to add my USB-printer with the webinterface of cups, but I can't choose USB as device for my printer.
But lsusb shows a connected printer:
| Code: |
router ~ # lsusb
Bus 005 Device 002: ID 04f9:0027 Brother Industries, Ltd
Bus 005 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000
|
Also a device for this printer exists:
| Code: |
router ~ # ls -al /dev/usb/lp0
crw-rw---- 1 root lp 180, 0 Feb 19 23:13 /dev/usb/lp0
|
I emerged cups with following useflags:
| Code: |
router ~ # emerge -pv cups
These are the packages that would be merged, in order:
Calculating dependencies... done!
[ebuild R ] net-print/cups-1.2.6 USE="dbus jpeg nls pam png ppds samba ssl -X -php -slp -tiff" 0 kB
|
Also USB-printer support is compiled in the actual used kernel:
| Code: |
router ~ # uname -r
2.6.19-gentoo-r5
|
This is the used cupsd.conf:
| Code: |

Maybe I should say this is a fresh installation.
I've searched this forum for any useful topics, but didn't found any... 
Any help is appreciated...
Sorry for my bad englisch

I hadn't installed gimp-print, but I emerged it now.
It still doesn't let me choose USB as device for the printer. |

you may want to restart cups after you emerge gimp-print

can you post what is shown when you try to add a new printer to the cups webadmin Add printer page.
Sinc you have you should get a drop down list for device that includes or something similar.
check whether udev has created /dev/usb/lp0 for you.
| Code: |
bash-3.2#ls /dev/usb*
/dev/usbdev1.1_ep00 /dev/usbdev2.1_ep81 /dev/usbdev3.2_ep00
/dev/usbdev1.1_ep81 /dev/usbdev3.1_ep00 /dev/usbdev3.2_ep01
/dev/usbdev2.1_ep00 /dev/usbdev3.1_ep81 /dev/usbdev3.2_ep82
/dev/usb:
lp0

the actual printer drivers is the next step. Not having a driver should not prevent you selecting the usb device. Even if you dont have the correct driver you should be able to install the printer in cups with a _wrong_ driver. Just to clarify the difference.
You could also download the TurboPrint demo drivers but you still need to solve the device issue independantly.
HTH.
PS one thing I just noted, I was printing an image and tried to add a new printer . When I came to the device list the usb was not present. I waited until the printing was finished , tryed to select the device again and there it was.
It seems it was not listed while it was busy. Is it possible that device is somehow busy (lsusb, usbview or other prog) and therefore not showing up?

Hello,
thanks for the replies.
From kernelOfTruth: | Quote: |
enable some more options for cups, just in case, these are mine:
Quote:
net-print/cups-1.2.7 USE="X dbus jpeg nls pam png ppds ssl tiff"
don't forget "etc-update" after an update & "/etc/init.d/cupsd restart" !
|
I will not enable the X useflag of this ebuild, because this system doesn't has any Monitor nor I want to waste hdd-space for an useless X-server. And tiff only adds support for tiff images according to the gentoo printing guide:
| Code: |
http://www.gentoo.org/doc/en/printing-howto.xml#doc_chap3
|
But after reading this guide _again_ I found this interresting:
| Code: |
To enable USB printing, you need USB support and USB printer support.
Code Listing 2.2: USB Port Printer Configuration
Device Drivers -->
USB Support -->
<*> Support for Host-side USB
(...)
--- USB Host Controller Drivers
(Select the HCD that your system uses. If you do not know which one
to select, run "lspci -v | grep HCI" from another terminal)
<*> EHCI HCD (USB 2.0) support ( or )
<*> OHCI HCD support ( or )
<*> UHCI HCD (most Intel and VIA) support
(...)
<*> USB Printer support
|
I have compiled EHCI HCD, OHCI HCD and UHCI HCD into my kernel, since I never bevore had any problems with this configuration. But this printing guide suggests to install only one driver.
As far as I know an USB 2.0 - Controller consists of two Controller on one chip... one USB 2.0 and one USB 1.1.
Also mounting of an USB-Stick is working, so I guess USB is working
But I will compile a kernel only with one of the USB Controller Drivers.
From Gentree:

I will post this when I'm at home again.
But thanks so far.
I don't think another program is blocking this device, since i don't have started anythink that needs usb support. |

EHCI or OHCI or UHCI doesn't sound reasonable. If your motherboard is capable of EHCI (USB 2.0) then it will also be capable of either OHCI or UHCI. Compiling all three into your kernel should make no difference as the kernel will chose the driver according to what it finds on its PCI scan.
On this machine, Intel CPU and chipsets, USB printing works and | Code: | CONFIG_USB_EHCI_HCD=y
CONFIG_USB_UHCI_HCD=y |
Another thing you might try is switching on your USB printer, making sure it is connected and running | Code: | # lpinfo -v
network socket
network beh
direct usb://EPSON/Stylus%20D88
network http
network ipp
network lpd
direct parallel:/dev/lp0
direct canon:/dev/lp0
direct epson:/dev/lp0
direct scsi
serial serial:/dev/ttyS0?baud=115200 |
You can also look in /var/log/messages and, around the time you switched it on or connected it, you should see something like | Code: | Feb 20 14:38:48 usb 3-1: new full speed USB device using uhci_hcd and address 2
Feb 20 14:38:49 usb 3-1: configuration #1 chosen from 1 choice
Feb 20 14:38:49 drivers/usb/class/usblp.c: usblp0: USB Bidirectional printer dev 2 if 0 alt 0 proto 2 vid 0x04B8 pid 0x0005 |
but this should be OK as you have the /dev/usb/lp0 device which shows that all the necessary settings in your kernel are there.
It may be that you are missing a library, cups depends on dev-libs/libusb, have you got it?
You can also try | Code: | $ /usr/libexec/cups/backend/usb
direct usb://EPSON/Stylus%20D88 "EPSON Stylus D88" "EPSON Stylus D88 USB #1" "MFG:EPSON;CMD:ESCPL2,BDC,D4;MDL:Stylus D88;CLS:PRINTER;DES:EPSON Stylus D88;" |
which should read all the information from the connected printer.

I can say from experience that having all three compiled shouldn't pose any problems as I currently have that setup in my computer and my printer works fine. They're probably just saying that because chances are that one day something will be incompatible and it's safer to say to just use the newest one (as the others would then be superfluous) I know this is a dumb question, but what it is your printer and have you checked to see if cups itself supports it?
(Also, side question: Wynn, what the hell is that a picture of?) |

If CUPS can see the printer through the USB port, then it should appear in the dropdown device list on the second page of "Add printer". This seems to be the sticking point. Running /usr/libexec/cups/backend/usb should give further evidence one way or the other.
| alienjon wrote: | | Also, side question: Wynn, what the hell is that a picture of? |
but the answer is in the ``signature''! If you watch Elephants Dream â you can download it from orange.blender.org â in the scene where Emo and Proog are going across the bridge, there are a number of mechanical birds swooping around. These are the "jorma" that they used in the film but, in the production materials, there is another version which ... well, I'm sure you can finish the story.

Well.... shame on me.... 
looks like cups always sends me the wrong url for the admin-pages... something like:
| Code: |
https://localhost:631/admin?OP=add-printer
|
this loads a cups page, sure... but not from my router...
so the problem changes...
How do I tell cups to send a valid url for its admin-pages? |

From what you say it sounds as if you have CUPS installed on your router (?)
Another thing, if you are doing remote admin using https you are going to need to create a certificate ... er ... perhaps, it seems to depend on whether gnutls is being used or not and it appears to be used.

I solved it with the help of this topic: 
https://forums.gentoo.org/viewtopic-t-519300-highlight-cupsd+ssl.html
the cups-server on my router (which is my cups-server for my home-network) tried do send a invalid url... which i corrected...
next problem was the one described in the topic i wrote above...
So thanks to everyone who helped me
