Lub tsev luam ntawv hnub no tsis yog ib qho khoom kim heev, tab sis yog ib qho tseem ceeb. Thiab tsis yog rau cov neeg ua haujlwm hauv tsev xwb, tabsis rau cov menyuam kawm ntawv, cov menyuam kawm ntawv thiab cov niam tsev.
Tej zaum koj twb muaj lub tshuab luam ntawv, thiab koj xav hloov nws. Thiab qhov no yog qhov tseeb, vim hais tias dhau los ob peb xyoos dhau los, tsis tsuas yog cov qauv tshiab ntawm cov npe twb paub rau koj nyob hauv lub ntiaj teb, tab sis kuj luam tawm raws li kev luam tawm tshiab. Noj tsawg kawg yog ib qho technology niaj hnub, uas muaj ntau yam nyob rau hauv ntau nrog ib lub laser. Nws yog suab nws ceg. Ob lub teeb-emitting diode thiab laser printers endowed nrog ib tug hluav taws xob ncej uas lub teeb qhov twg ua nyob rau hauv cov ntsiab lus zoo, "pasting" lub toner-hmoov mus rau lub qhov tob. Qhov no, laser yog siv los ua lub teeb ci rau laser printers, thiab rau cov LEDs - LEDs uas yog me ntsis tsis zoo dua rau laser nyob rau hauv qhov tseeb. Qhov no yog lawv lub ntsiab tseem ceeb. Tab sis qhov no technology yog tsawg zog-intensive, thiab tus ceev ntawm LED printers, lwm yam ua tau sib npaug, yog me ntsis siab dua laser counterparts. Txawm li cas los xij, lub tshuab luam ntawv laser tseem nyiam tshaj plaws, suav nrog lub tsev luam ntawv. Cov dluab luam tawm ntawm nws, ob qho tib si tsos nqaij daim tawv thiab dub thiab dawb, tsis ntshai hnub thiab noo noo, lawv tsis muaj bands. Tsis tas li ntawd, lub tshuab luam ntawv laser yog tam sim no muaj rau txhua tus neeg uas xav kom nws, nws tsis siv ntau qhov chaw ntawm lub desktop thiab muaj lub siab ceev ceev.
