PrinterInterface(GPIO)Specifications
ThePrinterElectricalSignalInterfaceandProtocolisdevelopedtocoordinatethe
printingoflabelswithanexternalprocessinaproductionworkflow.Usingthisprotocol,
theprinter(DeviceA)receivesaprintjobbutwi llnotprintuntilitreceivesasignalfrom
anexternaldevice(DeviceB).
Thefollowingscenarioillustrateshowthiscouldbeused:
1. Aboxonaconveyorarrivesataworkstation.Abarcodeisreadandtriggersa
messagetoacomputer.
2. Thecomputersendsaprintjob(probablywithsomevariabledata)totheprinter.
3. Theboxreachesthenextstationontheconveyorandtriggersasignal(e.g.bya
footswitchor
automaticallybyasensor).Theprinterstartsprintingwhenthesignal
isreceived.
Theelectricalsignaltoinitiateprintingisreceivedattheprinter’sGPIOport.The
handshakingprotocolisasfollows:
•TheprintersignalsitisreadytoprintbypullingupthePrintJobReadysignalfrom
lowtohigh.
• DeviceBsignalsitisreadybypullinguptheReadysignal.Thismustremainhighfor
atleast50msbef orereturningtolow.
•Theprinterprintsandpullsdownthesignalwhenprintingiscompleted.

DHCPSetting
2
SettheIPsettingsontheprinter.
• Automatic:SetDHCPservertoautomatic.
• Manual:DisableDHCPserverorallowusertosetastaticIP.
IPSettings
2
EnterthestaticIPsettingsfortheprinter.

1. Pressandtoseteachdigit(0to9).
2. Presstomovetothenextdigit.
1. RequiresSecurityLevel1(supervisor)orhighertochange.SomesettingsmaynotbeviewableatSecurityLevel0.
2. RequiresSecurityLevel2(administrator)tochange.SomesettingsmaynotbeviewableatSec urityLevels0and1.
