Digital BW, The Print

Daniel,

I don't have any great ideas.  If it happens on different printers and
on different inks, it seems hard to blame it on hardware.  The drivers
all put the ink down in their own way -- i.e. the microweave is a driver
software feature.   I guess its possible that gimp-print's method is not
as tolerant of some difference, but this isn't a common issue and you
say it used to be ok.

Have you used other papers, like matte?  Do the patterns show up then?
Have you cleaned underneath the heads, using a paper towel and
windex or some mild cleaner?
