[CentOS] [OT] Label Printer Recommendations

Greetings Folks,
 I am after any recommendations or experiences using Label printers to print 
barcodes with CentOS, we currently using Star TSP700's but they're not clear 
enough for the scanners we have. There seems to be plenty of choice but not 
much Linux support going on, 'Never had anyone ask for Linux drivers 
before..' seems to be the most common answer when trying to buy. I have also 
tried a Brother P-Touch QL-550 but can't seem to get that to print at all 
using the Foomatic drivers available online.

TIA

Colin.
