Bug Description

Binary package hint: splix

Dear Ubuntu folks:

Thank you for packaging all this good software for Ubuntu!

My Samsung ML-1740 isn't working very well with my new Natty computer. Inspecting the configuration, I see that it is using the GDI driver which is reputed to be problematic on The splix driver is recommended instead. I've always had excellent performance from using the splix driver with this printer in the past. So, for starters the default configuration of Ubuntu should probably be changed to use the Splix driver for this printer.

But in any case, I can't seem to find the Splix driver PPD within Ubuntu. The "splix" package is installed, but there are no PPD files in /usr/share/ppd/splix, nor any PPD files that I can find for ML-1740 or with the word "splix" anywhere in their name.

I know that in previous distributions of Ubuntu the "splix" package came with all the PPDs, then in later versions they came compressed, and then in the most recent version the source code comes with the package and the PPDs are supposed to be generated at install time. Maybe there is a bug in that process? That would explain the apparent absence of the needed PPD files here.

The PPD files are there, but in one compressed archive, /usr/lib/cups/driver/splix. You see the PPD files if you let CUPS list them via the command

lpinfo -m


lpinfo -m | grep 1740

in a terminal window and you see all possibilities for your printer.

When I run system-config-printer (I do not have any Samsung printer) and enter the URI "x:" under "Enter URI" I get into the step of manually choosing make and model. There I choose "Samsung" and "ML-1740". The SpliX driver appears there, but indeed the "gdi" driver is marked recommended. This wrong assignment is done by a prioritarization in system-config-printer, it seems to have gotten messed up on the recent change of handling driver priorities.

Moving the bug to system-config-printer ...

When I go through this process I do *not* see the splix driver in the system-config-printer GUI tool.

1. sudo apt-get install splix

2. zompu:~$ lpinfo -m | grep 1740
foomatic-db-compressed-ppds:0/Samsung-ML-1740-gdi.ppd Samsung ML-1740 Foomatic/gdi
splix:0/samsung/ml1740.ppd Samsung ML-1740, 2.0.0
splix:0/samsung/ml1740fr.ppd Samsung ML-1740, 2.0.0
splix:0/samsung/ml1740pt.ppd Samsung ML-1740, 2.0.0

3. unplug the USB cable so that system-config-printer won't autodetect my printer

4. $ system-config-printer

4. enter "x:" in the URI

5. Choose "Samsung" and "ML-1740".

Now I observe that ...

Oh, this one here named "Samsung ML-1740, 2.0.0 [en]" must be the splix driver. My mistake was thinking that one was just a variant of the GDI driver.

The problem is indeed a wrong prioritarization of SpliX. SpliX is assumed a non-free third-party driver which is not the case. It is released under a free license and therefore we ship it in main. SpliX should have a higher priority, as it is the best support for Samsung printers, it should be preferred against "Foomatic/gdi" (the other SmartGDI driver) and against PCL drivers (Samsung printers are better in Samsung's language than in PCL). In addition, the regexp to identify a PPD entry as a SpliX entry was wrong. The attached patch fixes this.

  * debian/patches/20_priority-for-splix.patch: Raised the priority of the
    SpliX driver for Samsung laser printers, so that it is used as the default
    driver for these printers, and not "Foomatic/gdi" any more (LP: #793741).
