When using the printer driver for the HP Laserjet 4100
printer
(http://www.linuxprinting.org/download/PPD/HP/mono_laser/HP_LaserJet_4100_Series.ppd),
I get the following error:
"PDD syntax error, UI specification not correctly closed"
This error is displayed on the console when printing in
kghostview, or it is displayed in a message box when
using Adobe Acrobat (Linux).
Upon examination of the file, the closing of the
HPwmBrightness seems to cause this problem. Apparently
the syntax is case-sensitive (the file uses
HpwmBrightness instead of HPwmBrightness).
I applied the patch attached to this message, and the
problem was solved to me. I didn't check whether other
HP printer drivers suffer from the same problem.
