還(huan)(huan)(huan)有(you)辦公用(yong)的(de)(de)(de)打(da)印(yin)(yin)紙(zhi)(zhi)，分類(lei)是按紙(zhi)(zhi)張(zhang)(zhang)的(de)(de)(de)大(da)小和(he)層數分的(de)(de)(de)，比如(ru)241-1，打(da)字(zi)紙(zhi)(zhi)生產廠家(jia)，241-2，它們(men)分別(bie)表示1層和(he)2層的(de)(de)(de)窄(zhai)行打(da)印(yin)(yin)紙(zhi)(zhi)，當然還(huan)(huan)(huan)有(you)3層4層的(de)(de)(de)；常用(yong)的(de)(de)(de)寬行打(da)印(yin)(yin)紙(zhi)(zhi)還(huan)(huan)(huan)有(you)381-1，381-2等。 還(huan)(huan)(huan)有(you)按紙(zhi)(zhi)張(zhang)(zhang)的(de)(de)(de)厚(hou)度來(lai)分的(de)(de)(de)，比如(ru)60g、70g、75g、85g、120g等等，是指在單(dan)(dan)位面積(ji)紙(zhi)(zhi)的(de)(de)(de)重(zhong)(zhong)(zhong)量(liang)是多重(zhong)(zhong)(zhong)，因(yin)為紙(zhi)(zhi)的(de)(de)(de)密度基本上(shang)是一樣的(de)(de)(de)，在單(dan)(dan)位面積(ji)紙(zhi)(zhi)的(de)(de)(de)重(zhong)(zhong)(zhong)量(liang)越重(zhong)(zhong)(zhong)，紙(zhi)(zhi)的(de)(de)(de)厚(hou)度就(jiu)越厚(hou)。比如(ru)一般速印(yin)(yin)機(ji)用(yong)的(de)(de)(de)是40g左右的(de)(de)(de)紙(zhi)(zhi)，而一體(ti)機(ji)用(yong)的(de)(de)(de)是50-60g的(de)(de)(de)紙(zhi)(zhi)，而復印(yin)(yin)機(ji)用(yong)的(de)(de)(de)是70-85g的(de)(de)(de)紙(zhi)(zhi)，打(da)印(yin)(yin)機(ji)用(yong)的(de)(de)(de)一般不要使用(yong)低于60g厚(hou)的(de)(de)(de)紙(zhi)(zhi)，否則就(jiu)容(rong)易卡紙(zhi)(zhi)。
