For HP LaserJet Series II and III printers using printer driver version 3.86, there are known problems at 150 dpi resolution. If you have selected 150 dpi, Time Line automatically switches to 300 dpi, which produces higher quality output. If your HP Series II or III printer has at least 3 megabytes of memory, you should not experience noticeable slowdown in printing speed. If you do experience a significant degradation in print speed, we recommend using 75 dpi for draft printing, and 300 dpi for final output. Of course the best solution of all would be to use a modem to download the latest version of the printer driver file, from the Microsoft Product Support Download Service.
