I've tried the HP profiles as well and yes - the B&W profiles from HP seem to be crap or I may misuse them completely
The best B&W results I get are without any tweaking simply applying the appropriate ICC profile for the used paper and print out of Photoshop or Lightroom with Application managed color and the appropriate setting s in the printer dialogue (the ones that have been indicated by the ICC profile or when you did the profiling)
Pre cautions have to be following:
1.) Do a printer test and look whether all print heads are working well?
2.) Do a print head alignment before every important printing job or whenever the printer rests for some weeks
3.) Do the self precalibration of the HP 130 built in linearisation fpr every new batch of paper
4.) Use either the HP paper and the appropirate profiles or do custom made profiles for your used paper
5.) Do the profiling of the papers with at least a drying time of 2 to 3 days
If you follow these steps you will experience fantastic B&W large format prints without having to manipulate in the printer menue.
Application managed color with the appropriate ICC profiles leads to outstanding prints with the HP 130 NR
hope this helps
