1. Ob chav offset daim ntawv: daim ntawv sau nyiaj ntsuab uas tsim los ntawm cov ntawv zoo tib yam ob chav offset yog tag nrho ib txheej, tsis muaj txheej txheej ntawm daim ntawv, thiab cov lus tau luam tawm los ntawm daim kab xev xim.
2. Cov ntawv thermal: cov ntawv sau nyiaj thermal uas tsim los ntawm kev ua cov ntawv thermal yog tag nrho ib txheej txheej, daim ntawv saum npoo yog coated nrog thermal chemical txheej, thiab daim ntawv yog xim los ntawm laser thermal lub taub hau. Nws yog tus cwj pwm los ntawm tsis muaj cov khoom siv luam ntawv, carbon ribbon, xim ribbon lossis number case cartridge; Ntxiv mus, qhov saum npoo ntawm daim ntawv yog tus du, thiab yuav muaj cov cim meej thaum nws khawb ntawm daim ntawv nrog rau tes los yog cov khoom tawv.
3. Carbonless ntawv: hom ntawv sau nyiaj ntsuab no muaj tsawg kawg yog ob lossis ntau txheej. Thawj tus xav tau lub tshuab luam ntawv koob los luam thiab tsim xim, tab sis cov tom qab tso siab rau kev luam ntawv siab ntawm lub tshuab luam ntawv koob los tsim xim.
4. Daim ntawv siab: daim ntawv sau npe nyiaj ntsuab no yog tsim los ntawm ib lossis ntau txheej. Cov xim yog tsim los ntawm kev luam ntawv siab los ntawm koob tshuab luam ntawv. Cov ntawv luam ntawv tsis tas yuav tsum tau nruab nrog cov xim band. Thawj daim ntawv luam ntawm daim ntawv sau npe nyiaj ntsuab no yog hu ua self sensing paper, thiab cov ntawv luam hauv qab no yog cov ntawv tsis muaj cov pa roj carbon zoo tib yam.
