Comment 3 for bug 1512012

For the USB issues of te different USB ports of your docking station behaving differently, open a bug on the Linux kernel (Ubuntu package "linux").

Your printing problem can be a bug in the printer's PostScript interpreter, so please follow the instructions of section "PostScript (PDF) printer chokes on the PostScript (PDF) coming from Ubuntu" on https://wiki.ubuntu.com/DebuggingPrintingProblems.

As a workaround you can always try PPDs/drivers for PCL 6/XL or PCL 5e/c (see the "Generic" printers if you do not find anything appropriate in your printer's entry).

Please post your results here.
