SP-Tseriesprintersareaseriesofdesk-topmicroprinterwhichare
with updateddesign.Theyarewith theseremarkablefeaturesofdelicate
dimension,perfectperformance,elegantappearance,simpleoperation,
convenient connection.
ThespecificationofSP-Tprintersiscomplete,youcanchoose
differentprintspeed,differentprint linewidth,differentprintfont,
different printbuffer,and differentinterface ofserialand parallel.So,these
printerscanbeasprintoutputdevicesofall kindsofintelligentinstruments,
metersand microcomputers.
SP-Tprinterscanbewidelyusedin manyapplicationareas.Theycan
print reportforms,payslip and recordpathologiccurvesofall kindsof
medicalinstrumentsandmeters.Theyalsocanprint15kindsofdifferent

and needn’taltertheprintingdriverprogram oforiginalsystem.Moreover,
owingtoadoptqualifiedESC standardcontrol codecommands,SP-Talso
canreplace 9-pin printers.
SP-Tprintershavefivemodels;two kinds ofinterface:serial,parallel;
three levelsofprint buffer:2Kbytes,8Kbytes,32Kbytes;52control

1.1Modeldefinition
SP-Tprintershavefivekindsofprintheadmodelandtwo kindsof
interface.Theyare definedas:
SP-T()

YoucancompareyourSP-Tmicroprinter withtheabovedefinition,soas
tocorrectlyreadand understand thecontents in this manual.
1.2Interface

compatiblewith RS-232C.Thetwokindsofinterfaceareconnectedtothe

1.3PrinterCodes
SP-Tprintersoffer 448kindsofinternalcharacters,includingEnglish,
Greek,German,French,JapanesekatakanaandGBChinesecharacter
librarylevelI,II,alargenumberofmathematicssymbols,special-purpose
symbolsand various kindsofgraphicandcurvingsymbols.All the
charactersare composedbytwo character sets(seeAppendix 1), chosenby
thehost’sprogramsthrough control commands.Character size is5 ×7
dots,graphiccharactersize is6×8dots,throughcertainprograms,also

candefine32 kinds ofcharacter, soastosatisfyyourparticular needs.
SP-Tprintersalsooffer graphicsprintmode,charactersand graphicscan
beprintedtogether.
1.4Print Commands
SP-Tprintersoffer 52 kindsofprint command.Mostofthem are
compatiblewiththecommandstandardofIBM andEPSONprinter.
Combiningmicroprinter’sfeaturesandapplication situation,SP-Tadd
somecommandsthatareconvenient forusing,suchasprintcurve
commandetc.Therefore,SP-Tcanreplace most9-pinor24-pinprintersto
beuseddirectly,onlybydoingalittleadjustmenttotheoriginalprint

printinggraphicsand curves, youmayfeelit is more convenient.
Ifyouhaveever usedSP-40orSP-16 microprinter,youwill find SP-T
printersarefullycompatiblewith theprintcommands ofSP-40orSP-16,
and charactersare more abundant, pleasesee 3.6ofChapter3fordetails.
1.5WorkingMode
SP-Tprintershavesixkindsofworkingmode,theyare:hexadecimalprint
mode,characterprint mode,graphicsprint mode,self-testmode,on/off
linemodeandpaper feedingmode.Amongthem theanteriorthree kindsof
modecanbechangedbycontrol commands,theposteriorthreeonescanbe
realizedbybuttonoperation. Pleaserefer toChapter 3and Chapter 4.
1.6Offline Print
Forsome printersinSP-TseriessuchasSP-T40,theprint speedisabit
slow.However,SP-Tprintersadoptadvanceddesign method,provide
ratherbigprintbuffer, sothatthehostcanfinishthedataexchangewiththe

2.2CheckingAccessories
There is alreadyapaper roll and ribbonis installedin theprinter at
ex-factory, and a User sManual aswell. Youcanalsochooseother
accessoriesaccordingtoyourrequirements. (see Appendix 5)
2.3RibbonCassette Installation
Theribbon cassettehasalreadybeeninstalledwell atex-factory,but after
usingforaperiodoftime,it needstochangetheribbon cassette,theways
forchangingribboncassettemayaccordtothefollowingsteps:
(1)Takedownthemovablecover paneloftheprinter asFig.2-2shows;
whatFig2-3showsis wrong.

2.4PaperRoll Installation
ForSP-Tprinters, paper roll canbeput insidethecase, installingpaper as
follows:
(1)Push theremovablecover plateforwardtill it off theprinter like
Fig.2-2,
(2)Cut thepaper end likeFig.2-10 below.
Forpaper roll placedinsidethecase:Insertthepaper end downwards into
paper-in slotonrear ofprinter mechanismlikeFig. 2-11, Fig.2-12 paper
upwardis notcorrect.
Forpaper roll holdoutsidethecase:firstlyput paper throughthenarrow
orifice thatis atthebackofprinter shell, asshownin Fig2-12, thenmake
paper face thepaper-in slot.

thebutton<LF>torun theprint head, and theninsertthepaper intothe
paper-in slot,and thepaper will beloadedintotheprint headand come out
fromthefront foracertain seemlylength.
(5)Press LForSELbuttonagain orturnthepower off.
(6)Put paper end throughthepaper-out slotthatonthemovablecover
panel, and closethemovablecover panel.
2.5PowerSupply
SP-TprintersadoptDC+5Vpowersupply.Itisrecommendedtousethe
power connectorthatmatcheswell totheprinter,sothatyoucandirectly
connecttheplugofconnecter tothesocketofprinter.If useother power
supply,itsvoltageishigherthan5.5Vorlower than4.5V,andcurrentis
lower than3A,wewon’tguaranteetheprinterworks normally,evenmay
damagetheprint head.
Pleasenotethatthepolarityofthepowershouldn'tbeconnected
incorrectly.
