I think that gutenprint is the correct driver for your printer and this page |
| 8 |
also suggests the same: |

However, this might have been the case before the latest cups version - so |
| 13 |
some further testing will be required (see below). |

This is the cups driver (in kernel) which ought to pick up your usb printer |
| 20 |
and use it without problems. However, according to your logs ... there seems |
| 21 |
to be a clash: |

So, what happens if you build usblp as a module and you modprobe -rv ubslp? |
| 28 |
Does cups pick up your printer now? |

I suspect that this was created by the gutenprint driver that you installed. |
| 37 |
I believe that if you resolve the usblp error first then you'll know if |
| 38 |
gutenprint is necessary or if it will work. Some manual tweaking of the ppd |
| 39 |
file may also be needed to print in higher resolutions, but let's get it to |
| 40 |
print first. |

Stop press! |

I just checked again your first post: You are using cups 1.4 which accesses |
| 45 |
raw usb devices! Definitely remove usblp (or blacklist it and reboot if you |
| 46 |
don't want to recompile your kernel, or can't modprobe -r) and see if the cups |
| 47 |
back end picks up your printer on its own. |
