I have a HP LaserJet 4050 that has been working very well with my computer. A few months back I ran out of ink so its been sitting until last week. I put the ink in and I couldnt print.

I was checking things out and I found this:

Code:

In /var/log/syslog I have hundreds of lines with this:

Code:

Jan 23 10:23:17 wadesmart kernel: [ 3099.402989] usb 1-1: new full speed USB device using uhci_hcd and address 41

Jan 23 10:23:18 wadesmart kernel: [ 3100.333105] usb 1-1: device not accepting address 42, error -71

In cups the address of the printer is:
Device URI:
hal:///org/freedesktop/Hal/devices/usb_device_4348_5584_noserial_if0_printer_noserial

Now, if I have the cable plugged in to any of the six usb ports with or without the printer on, it immediately starts adding the above entries to the system log.

I have obtained a serial to usb cable that I might try later.

Try deleting the printer in CUPS (localhost:631), then plug it in, then if all goes well add it in CUPS again.

One of the first things I tried... well.. almost one of the first.

I have also changed the ownership of some of the ports.
Found a older post about using a serial printer so Im trying to see if that will work for me.

I found that link in the forums and I have been following along what
they were doing.

The last bit: creating a link from one file to the other:
This:
-s /usr/lib/cups/backend-available/serial /usr/lib/cups/backend/serial

produces this:

wadesmart@wadesmart:/usr/lib/cups/backend-available$ sudo
/usr/lib/cups/backend-available/serial /usr/lib/cups/backend/serial
Usage: /usr/lib/cups/backend-available/serial job-id user title copies
options [file]

So I thought they meant do sudo :

wadesmart@wadesmart:/usr/lib/cups/backend-available$ sudo -s
/usr/lib/cups/backend-available/serial /usr/lib/cups/backend/serial
/usr/lib/cups/backend-available/serial:
/usr/lib/cups/backend-available/serial: cannot execute binary file
wadesmart@wadesmart:/usr/lib/cups/backend-available$
