What you may want to try is opening the USB serial port with minicom and then exiting. Be sure to configure minicom with the correct serial port settings and flow control (on a separate page). Delete the modem initialization string as well. Once minicom has initialized the port and you have exited, you will see some junk characters on your first print out (naturally) but subsequent print outs should be okay.
I have noticed that CUPS appears to not initialize the USB serial port correctly anymore. The version of CUPS shipped with Fedora 11 worked fine. It is also possible that the kernel USB serial driver changed and now requires more initialization. Please have a look at the Fedora bug I filed: https://bugzilla.redhat.com/show_bug.cgi?id=624564 Thanks to Jiri Popelka for pointing out this ticket. ** Bug watch added: Red Hat Bugzilla #624564 https://bugzilla.redhat.com/show_bug.cgi?id=624564 -- Ubuntu 10.04 does not recognize local printer (HP Laserjet 4) connected via USB. https://bugs.launchpad.net/bugs/564917 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
