<P>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;我在m28a打印机在mac系统上安装的过程中出现了上述问题，在搜索惠普社区的时候发现有人有同样的问题，但是问题至今未解决，以下是为该帖子的链接<A

此外，我还有出现的问题是macbook无法使用m28a打印机进行手动双面打印。</P><P>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 我对这个问题有一些个人的猜测，我看到mac系统里的hp打印机驱动是HP Laser Jet MFP M28-31，而打印机本身的型号是HP Laser Jet Pro MFP M28a，是不是驱动本身出了问题？我尝试了安装HP Laser Jet <STRONG>Pro</STRONG> MFP M25-M27的驱动，发现其可以选择是否双面打印，但是实际无法打印。然而HP Laser Jet Pro MFP M28a在mac系统里无法弹出这个选项，也因此无法手动双面打印。上述问题在windows系统中都不曾出现，还请您帮忙解决，感谢！</P> Fri, 05 Aug 2022 15:14:54 GMT

<P>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 而且我还有一些比较不专业的想法，我猜想打印机之所以有HP LaserJet MFP和HP LaserJet Pro MFP之分，就在于前者只支持简单的单面打印功能，不支持手动双面打印或者扫描功能，而Pro相比于前者即增加了手动双面打印功能和扫描功能。但是我们不难发现mac系统上的驱动仅有HP LaserJet MFP M28-M31，而我在惠普官网上找到的驱动却是HP LaserJet Pro MFP M28-M31，那是不是mac系统上的驱动程序本身就出错了，本身就没有将手动双面打印功能和扫描功能写进驱动里面呢？如果是这样的话，还是希望惠普打印机的工程师能够修复mac系统上的这个驱动bug，感恩！</P> Fri, 05 Aug 2022 15:27:01 GMT
