Thermal printers tau siv ntau xyoo, tab sis tsis tau siv rau kev luam ntawv barcode zoo txog thaum xyoo 1980s.Lub hauv paus ntsiab lus ntawmthermal tshuab luam ntawvyog lub tsho tiv no lub teeb xim (feem ntau yog daim ntawv) nrog lub pob tshab zaj duab xis, thiab ua kom sov cov zaj duab xis rau ib lub sij hawm ntawm tig mus rau hauv ib tug tsaus xim xim (feem ntau yog dub, tab sis kuj xiav).Cov duab yog tsim los ntawm cua sov, uas ua rau muaj tshuaj lom neeg cov tshuaj tiv thaiv hauv zaj duab xis.Cov tshuaj tiv thaiv no yog ua tiav ntawm qhov kub thiab txias.Qhov kub thiab txias ua rau cov tshuaj tiv thaiv no.Thaum qhov kub thiab txias qis dua 60 ° C, nws yuav siv sij hawm ntau heev, txawm tias ob peb xyoos, rau zaj duab xis kom tsaus;Thaum qhov kub thiab txias yog 200 ° C, cov tshuaj tiv thaiv no tiav nyob rau hauv ob peb microseconds.Covthermal tshuab luam ntawvxaiv heats cov ntawv thermal ntawm qee qhov chaw, yog li tsim cov duab sib xws.Cov cua sov yog muab los ntawm lub tshuab hluav taws xob me me ntawm lub taub hau luam ntawv uas yog nyob rau hauv kev sib cuag nrog cov khoom siv cua sov.Lub tshuab cua sov yog qhov tsim nyog los ntawm lub tshuab luam ntawv hauv daim ntawv square dots lossis strips.Thaum tsav tsheb, ib daim duab sib thooj rau cov khoom cua sov yog tsim rau ntawm daim ntawv thermal.
Tib lub logic uas tswj cov cua sov kuj tseem tswj cov ntawv pub, tso cai rau cov duab luam tawm ntawm tag nrho daim ntawv lo lossis daim ntawv.Lub tshuab luam ntawv thermal feem ntau siv lub taub hau luam ntawv ruaj khov nrog lub rhaub dot matrix.Lub taub hau luam tawm hauv daim duab muaj 320 square dots, txhua qhov yog 0.25mm × 0.25mm.Siv cov dot matrix no, lub tshuab luam ntawv tuaj yeem luam tawm ntawm txhua txoj haujlwm ntawm daim ntawv thermal.Cov tshuab no tau siv rau ntawm cov ntawv luam ntawv thiabdaim ntawv lo tshuab luam ntawv.Feem ntau, daim ntawv pub ceev ntawm lub tshuab luam ntawv thermal yog siv raws li qhov ntsuas ntsuas, uas yog, qhov ceev yog 13mm / s.Txawm li cas los xij, qee lub tshuab luam ntawv tuaj yeem luam tawm ob zaug sai dua thaum daim ntawv lo ua kom zoo dua.Cov txheej txheem thermal tshuab luam ntawv no yog qhov yooj yim, yog li nws tuaj yeem ua rau hauv lub tshuab luam ntawv roj teeb ua haujlwm thermal.Vim yog hom ntawv hloov tau yooj yim, cov duab zoo, kev kub ceev thiab tus nqi qis uas luam tawm los ntawm cov tshuab luam ntawv thermal, cov ntawv cim barcode luam tawm los ntawm nws tsis yooj yim rau khaws cia rau hauv ib puag ncig siab tshaj 60 ° C, lossis raug ultraviolet lub teeb (xws li ncaj qha hnub ci) rau lub sijhawm ntev.lub sijhawm khaws cia.Yog li ntawd, cov ntawv thermal barcode feem ntau yog txwv rau kev siv sab hauv tsev.
