Here is dmesg}tail from an unplug-plug of the USB cable [20091.736439] usb 2-1.1: USB disconnect, device number 21 [20096.780904] usb 2-1.1: new full-speed USB device number 22 using ehci-pci [20096.872367] usb 2-1.1: New USB device found, idVendor=050d, idProduct=0002 [20096.872375] usb 2-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [20096.872379] usb 2-1.1: Product: IEEE-1284 Controller [20096.872382] usb 2-1.1: Manufacturer: Belk USB Printing Support [20096.878554] usblp 2-1.1:1.0: usblp0: USB Bidirectional printer dev 22 if 0 alt 1 proto 2 vid 0x050D pid 0x0002 [20098.008729] usblp0: removed [20098.020422] usblp 2-1.1:1.0: usblp0: USB Bidirectional printer dev 22 if 0 alt 1 proto 2 vid 0x050D pid 0x0002 [20098.217202] usblp0: removed You'll note that the USB device is a "controller" not the actual printer. The "controller" is a USB-parallel adapter to the printer, an HP LaserJet 1300. Some data. Printing is sporadic. Mostly the job just hangs, but sometimes it actually prints. "Self test" (from Administration=>Print Settings) works, but "test Page" does not. "cat foo | lpr" hangs. All of this is from Fedora 19. Under Fedora 17 printing often worked, but always worked if I plug-unplug the USB cable. I'm puzzled by the last "usblp0: removed". It seems that this is consistent with the behavior, but I have no idea what it would happen. Suggestions as how to proceed would be appreciated. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
