Bug Description

Hello,
This printer is detected in Ubuntu/CUPS, however it will not actually print anything succesfully. It prints about half the page and then has an error and stops printing altogther leaving the page in a half-inky mess. The printer works perfectly on Windows XP etc.
I ran hp-check and was unable to get this device detected properly by HPLIP after a considerable amount of trying; the device is plugged in via a USB-to-Parellel port: Bus 004 Device 002: ID 067b:2305 Prolific Technology, Inc. PL2305 Parallel Port

Useful config files attached. HP-Check Notes: dbus and libusb are installed but not detected. I also added my username to the lp and lpadmin group, which appears perfeclty in users & groups but keeps throwing an error on lp group for me regardless.

I read here: http://unix.stackexchange.com/questions/62523/how-to-install-a-printer-that-is-connected-via-an-usb-to-parallel-port-adapter -- that it may be possible to do some hardcoding to make it work, but it didn't look like the correct way of doing it. So I am hoping someone will be able to properly debug this issue.

Thanks in advanced! :)

As far as I know HPLIP does not support printers through USB->Parallel adapters.

To the HPLIP developers at HP: Is this the case? What about adding such support?

G4JC, which version of Ubuntu are you using? Can you try a live CD/USB stick of a newer version?

This is using Ubuntu 12.04.3 LTS (Precise Pangolin); newer versions of Ubuntu seem to have the same problem. It can print through CUPS but not through HPLIP and hence crashes during a print job.

G4JC, thank you for the additional info. If HP does not introduce support for their printers through USB->Parallel adapters, stay with your current solution to print through CUPS ("usb" backend). Do not try to set up your printer via hp-setup or with the "hp" backend (HPLIP in device selection of system-config-printer).

Hello G4jc,
Thank you for submitting this bug and reporting a problem with hplip. You made this bug report some time ago and Ubuntu and hplip have been updated since then.

Could you confirm that this is no longer a problem and that we can close the ticket?
If it is still a problem, are you still interested in finding a solution to this bug?
If you are, could you let us know and, in the current version, could you run the following (only once):

Thank you again for helping make Ubuntu and hplip better.

My old HP2100M will work with the CUPS foomatic drivers over usb-to-parallel, but is exceptionally SLOW...

've made changes to the musb.c to recognize and work with the Prolific usb-to-parallel adapter to drive my older HP 2100M.

Your-mileage-may-vary.

Prolific is a usb-to-parallel adapter with vendor=0x67b / product=0x2305

Attached code for version HPLIP-3.23.3 - io/hpmud/musb.c only. Not sure how to do a patch.

From high level:
1. Obtain the printer model, serial number from the printer/usb endpoint itself and not the prolific's usb enumeration
2. Clear the halt when closing the raw data channel if talking to the prolific
