We have a couple of HP 315L printers and just recently started having an issue with one of them when printing on HP poster media. We do not use take-up reels because for us, they are a hassle because we do alot of short print runs. Anyway, we have never had issues with the media, but recently one of the printers is having issues advancing the media. It starts off O.K. and then it will print over and over on the same spot and not advance properly. The other printer which is the same exact model, etc, profiles, does not have this issue. Any suggestions? Other media is advancing just fine in it, so I am guessing that it is a setting that we are overlooking.
