Dot matrix printers yog qhov qub tshaj plaws nyob rau hauv kev siv niaj hnub no. Lawv teeb cov duab rau ntawm daim ntawv nyob rau hauv daim ntawv ntawm cais tsuas me me nyob rau hauv ib tug txawv yam. Cov thev naus laus zis niaj hnub no tseem niaj hnub siv, tab sis tseem siv rau hauv rooj plaub uas qhov pheej yig loj luam ntawv hauv ntau loj yog yuav tsum muaj nrog rau qhov yuav tsum tau tsawg rau qhov zoo ntawm daim ntawv tau txais.
Dot matrix printers tshwm sim xyoo 1964. Lawv lub zog yog tsim los ntawm cov kws tsim choj ntawm Seiko Epson Corporation. Nyob rau hauv no ntawm lub tshuab luam ntawv siv tshuab rau kev tsim cov duab, muaj lub taub hau luam ntawv, uas muaj ib txheej ntawm rab koob. Lub taub hau no yog tsau rau ntawm cov carriage, qhov txav uas yog teeb tsa los ntawm cov kev taw qhia nyob thoob plaws daim ntawv ntawm cov khoom thauj. Cov koob uas tsim los ua lub taub hau yog tsav los ntawm xaim hluav taws xob. Hauv kev hais ua ntu zus, cov koob txhaj tawm daim ntawv los ntawm tus number case ribbon. Cov ribbons no tau siv rau hauv cov tshuab luam ntawv ib txwm muaj thiab muab nkag rau hauv daim cartridges. Yog li, ib qho bitmap yog tsim. Kev lag luam tawm ceev ntawm cov luam ntawv siv cov thev naus laus zis yog ntsuas hauv cov cim ib thib ob, lossis CPS. Dot matrix printers tso cai rau koj luam tawm xov xwm ntawm cov thicknesses sib txawv, uas lawv tau nruab nrog cov txheej txheem los kho qhov sib txawv nruab nrab ntawm daim ntawv yob thiab lub taub hau luam ntawv. Cov kev daws teeb meem luam tawm ntawm lub tshuab luam ntawv dot matrix, zoo li lub luam tawm ceev, nyob ntawm tus naj npawb ntawm rab koob hauv lub taub hau luam ntawv. Cov tshuab luam ntawv tshaj plaws muaj 9 thiab 24-tus pin taub hau. 9-pin printers muaj kev kub ceev luam ntawv ntawm qib qes. Whereas 24-pin printers muaj cov ntawv luam zoo, tab sis ntau ntau nrawm dua. Cov tshuab luam ntawv rau dot matrix tshuab luam ntawv tsuas yog yob lossis perforated fanfold ntawv. Thaum siv daim ntawv foos, feem ntau cov qauv yuav tsum muaj phau ntawv xov. Qee cov qauv muaj nruab nrog txiav-daim ntawv tsis siv neeg cov cav feeder mechanism. Ntau hom xim luam tawm kuj tseem siv tau teev dot matrix tshuab luam ntawv. Qee cov qauv muab cov kev xaiv ntawm kev siv plaub-xim CMYK ribbon. Txhawm rau hloov cov xim hauv cov luam ntawv zoo li no, ib lub tshuab muaj peev xwm tau muab uas tshem tawm daim cartridge nrog cov pob txha caj qaum rau hauv nws ntu ntawm lub taub hau luam tawm. Ntawm qhov xim dot matrix tshuab luam ntawv, koj tuaj yeem tau 7 xim. Hauv qhov no, 4 hom xim luam tawm hauv ib qho hla, thiab xim ntxiv - hauv ob. Multicolor dot matrix luam ntawv tuaj yeem tsim cov ntawv luam tawm ntawm cov ntawv luam xim lossis cov duab yooj yim, tab sis nws tsis tsim rau kev tsim cov yeeb yuj, cov duab muaj tseeb. Hauv qee cov qauv, muaj peev xwm ntawm cov xim luam ntawv tag nrho tau paub nrog kev pab ntawm cov khoom siv ntxiv. Vim tias qhov tshwm sim ntawm cov xim inkjet luam ntawv, uas yog tus yam ntxwv ntawm kev ua tau zoo dua, dot matrix xim tshuab luam ntawv yog xyaum tsis tau siv.
