FWIW, it seems to work with cups with the following configuration in /etc/cups/printers.conf
(I just let the printer acquire an IP from the dhcpd server on the lan, and let cupsd discover the new printer, and tried gutenprint-ijs-simplified.5.2 as the driver for it from package net-print/gutenprint-5.2.7) Note is that cupsd automatically discovered the following protocol to talk to the printer (I tried others with no luck): lpd://<host>:515/PASSTHRU # cat /etc/cups/printers.conf # Printer configuration file for CUPS v1.4.8 # Written by cupsd on 2011-09-09 22:34 # DO NOT EDIT THIS FILE WHEN CUPSD IS RUNNING <Printer Epson_Stylus_Office_BX525WD> Info Epson Stylus Office BX525WD Location MakeModel Epson WorkForce 600 Foomatic/gutenprint-ijs-simplified.5.2 DeviceURI lpd://192.168.0.26:515/PASSTHRU State Idle StateTime 1315596829 Type 8425484 Filter application/vnd.cups-raw 0 - Filter application/vnd.cups-postscript 100 foomatic-rip Filter application/vnd.cups-pdf 0 foomatic-rip Accepting Yes Shared No JobSheets none none QuotaPeriod 0 PageLimit 0 KLimit 0 OpPolicy default ErrorPolicy stop-printer Attribute marker-colors \#000000,#FF00FF,#FFFF00,#00FFFF Attribute marker-levels 100,100,100,100 Attribute marker-names Black Ink Cartridge,Magenta Ink Cartridge,Yellow Ink Cartridge,Cyan Ink Cartridge Attribute marker-types inkCartridge,inkCartridge,inkCartridge,inkCartridge Attribute marker-change-time 1315596829 </Printer>
