The problem is that there are 2 printers magicolor 2430 DL which are not compatible, the PPD for the older model is located under Minolta and the PPD for the newer model is located under KonicaMinolta.
According to http://www.linuxprinting.org/show_printer.cgi?recnum=KonicaMinolta-magicolor_2430_DL: Note that the older Minolta magicolor 2430 DL and the newer Konica Minolta magicolor 2430 DL are not 100% equal. So it is not sure whether the Minolta magicolor 2430 DL perhaps also works with the driver from Konica Minolta. Konica Minolta also provides the rastertokmXXXXdl driver for newer printer models. This driver is released under the GPL, it would be nice if somebody could package this driver for Ubuntu. -- Konica Minolta is named twice in the manufacturer menu https://launchpad.net/bugs/64046 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
