I have just finished etching my first board. What an adventure. I discovered that my printer prints in higher resolution when printing from Windows, even though there aren't really any resolution settings to be found. I printed a test pattern on transparent paper and immediately forgot to flip it. I'm not too thrilled with the printing quality (imo its a bit smudgy sometimes) but the fine features are definitely there. I exposed the 4 different sections in 10 second intervals, so the last section got 40 seconds of exposure. Two of the sections didn't develop at all. I also forgot to press down the PCB to the design so that has definitely impacted quality.. I think both the exposure and maybe development time could have gone a bit longer. But i'm very pleased with how this came out! It seems i immediately got into the right ballpark with timing and concentrations!
