I was trying to use the driverless thing in CUPS to be able to add 
AirPrint printers on my network but 'driverless list' would never 
show any printers even with Avahi running.

Turns out the driverless binary is shelling out to ippfind and 
passing a long string of args to act as a filter, and that filter 
depends on echo having an -e flag to print in a format that 
driverless reads back.  Since we don't have -e, it was just reading 
back garbage.

    ippfind -T 0 _ipps._tcp _ipp._tcp ! --txt printer-type --and \( --txt-pdl image/pwg-raster --or --txt-pdl application/PCLm --or --txt-pdl image/urf --or --txt-pdl application/pdf \) -x echo -en '\n{service_scheme}\t{service_name}\t{service_domain}\t{txt_usb_MFG}\t{txt_usb_MDL}\t{txt_product}\t{txt_ty}\t{service_name}\t{txt_pdl}\t{txt_UUID}\t{txt_rfo}\t' \; --local -x echo -en L \;

The easiest solution seemed to be to depend on gecho from coreutils 
but maybe there's a shorter path.
