Black and white speed against color documents and a bigger feature set.
Verdict
Buy the HP LaserJet MFP M235sdw if you print mostly black and white documents and want fast 2-sided printing: HP lists up to 28 pages a minute single-sided. Buy the HP OfficeJet Pro 9135 if you need color, a fax, a 2-sided document scanner and two 250-sheet trays. LaserJet is the text workhorse and OfficeJet is the color all-rounder.
HP uses LaserJet for toner-based laser printers and OfficeJet for inkjets. The two lines overlap in the home-office market, so people often ask which to buy. The answer depends on whether you need color.
