I own an Epson Stylus CX4800, connected via USB, which worked perfectly under CUPS 1.1.23. Upon upgrading to 1.2.6 (and a subsequent test of 1.2.7) printing no longer worked at all. Sending a job to the printer was successful, but the printer never reacted. In the CUPS web interface, the message "Printer not connected; will retry in 30 seconds..." was received. Reconnecting and power on/off of the printer resulted in no improvement. No error messages were logged in the cups logs. With some searching online, I came around the possible workaround of changing the DeviceURI to file:/dev/usb/lp0, upon which the printer immediately woke up and started printing my jobs. Before the change, printers.conf looked like: <Printer Epson> Info Epson DeviceURI usb://EPSON/Stylus%20CX4800 State Idle StateTime 1166596776 Accepting Yes Shared Yes JobSheets none none QuotaPeriod 0 PageLimit 0 KLimit 0 OpPolicy default ErrorPolicy stop-printer </Printer> and the only change made it: <Printer Epson> Info Epson DeviceURI file:/dev/usb/lp0 State Idle StateTime 1166596776 Accepting Yes Shared Yes JobSheets none none QuotaPeriod 0 PageLimit 0 KLimit 0 OpPolicy default ErrorPolicy stop-printer </Printer> In my mind, it seems like the CUPS USB backend is broken, which is sortof odd since the backend CAN see the printer: # lpinfo -v network socket network beh direct usb://EPSON/Stylus%20CX4800 network http network ipp network lpd direct scsi serial serial:/dev/ttyS0?baud=115200 file cups-pdf:/ network smb # /usr/libexec/cups/backend/usb direct usb://EPSON/Stylus%20CX4800 "EPSON Stylus CX4800" "EPSON Stylus CX4800 USB #1" "MFG:EPSON;CMD:ESCPL2,BDC,D4,ESCPR1;MDL:Stylus CX4800;CLS:PRINTER;DES:EPSON Stylus CX4800;"
Created attachment 104420 [details] emerge --info Not sure how useful my emerge --info is, but here it is.
When printing from a Windows XP machine via IPP, this same system exhibits the exact behavior described in bug 156421: http://bugs.gentoo.org/show_bug.cgi?id=156421
Last comment can be fixed by uncommenting: application/octet-stream application/vnd.cups-raw 0 - in the /etc/cups/mime.convs file.
Same problem with Epson RX500. What kind of information would help?
I just did an 'emerge -uD world" and several packages were updated. Suddenly, my USB-Printer (Epson Stylus Color 830U) stopped working and CUPS gave me the error message "printer not connected, retrying in 30 seconds". I downgraded packages like sysfsutils, usbutils, libusb and so on, but it didn't help. In the Gentoo-Forums I found that thread: http://forums.gentoo.org/viewtopic-t-504442.html At the bottom of page 1 it says: > My fix was to replace usb://dev/usb/lp0 with file://dev/usb/lp0 in deviceURI So I edited /etc/cups/printers.conf manually and filled in "file://dev/usb/lp0" in deviceURI. So the printer works again for me.
That does not work with me. The DeviceURI of my printer is usb://EPSON/Stylus%20Photo%20RX500. I changed it to file://EPSON/Stylus%20Photo%20RX500 but cupsd would not start... I have an additional error message is printer' s status: 'Ready: /usr/libexec/cups/filter/rastertoprinter failed'
Don't change it to "file://EPSON/Stylus%20Photo%20RX500", replace that with "file://dev/usb/lp0" (or the corresponding device). Could you try that?
I tried that too. The job does not start, and i get the same error as in my previous post.
OK, maybe this is a stupid question, but did you restart cups with "/etc/init.d/cupsd restart"? And look in /dev/usb/ if you've got a device called lp0.
Yes, i did! :) /dev/usb/lp0 exists: crw-rw---- 1 root scanner 180, 0 2007-01-30 07:10 lp0 I don' t know if this helps, but i use gimp-print-4.2.7.
Since I'm just a simple user, the only thing I can see is, that my permissions on /dev/usb/lp0 are different to your ones: tekknokaetzi@hardcore ~ $ ll /dev/usb/lp0 crw-rw---- 1 root plugdev 180, 0 31. Jan 18:29 /dev/usb/lp0 tekknokaetzi@hardcore ~ $ groups disk lp wheel floppy audio cdrom video games usb users lpadmin portage scanner music camera plugdev modem vmware Your lp0 is in scanner group, mine is in plugdev group. I found 2 threads in the Gentoo-Forums: http://forums.gentoo.org/viewtopic-t-519881.html --> look at page 2 http://forums.gentoo.org/viewtopic-t-521190.html I really hope, that this helps you!
It might be a permision problem, but RX500 is a multimachine so i don' t know if group scanner is the correct one... I really appreciate your help! :)
I have similar problem, but in my case, putting file://... instead of usb://... won't work :-( the problem is that the printer driver expects the printer on /dev/lp0 by default but the Gentoo udev rules put it to /dev/usb/lp0 and cups does not pass the device parameter to the driver the cups error log says: renderer command: gs -q -dNOPAUSE -dPARANOIDSAFER -dBATCH -sDEVICE=pbmraw -dDEVICEWIDTHPOINTS=612 -dDEVICEHEIGHTPOINTS=792 -r600 -sOutputFile=- - | min12xxw -m 1300W -f letter -r 600 -p normal -t auto ... there is clearly missing the parameter "-d /dev/usb/lp0" this has an easy workaround by putting SYMLINK+="%k" into udev usb lpX rule

(In reply to comment #14) > > this has an easy workaround by putting SYMLINK+="%k" into udev usb lpX rule > > > So that workaround works for you? Can you print normally? yes, if there is a symlink /dev/lp0 to /dev/usb/lp0 and the device is writable by the group lp, I can print normally p.s. I forgot to mention explicitly that I use Konica-Minolta PagePro 1300W but the symptoms look the same, and it worked with older system setup (don't know if the CUPS version is the only thing to blame ...)

I expected it to get fixed with new versions of cups or gimp-print, it never happened. I noticed that foomatic-config sets the DeviceURI to usb:/EPSON/printer_model, so each time I was replacing it with usb:/dev/usb/lp0. It never occurred to me to use what I was using with foomatic-config, namely: -c file:/dev/usb/lp0 So, maybe the problem is in foomatic-config Thank you!

people say it is fixed :)
