Recently we decided to replace the old HP
Laserjet-3 printers which are used to plot vnmr
NMR spectra from our Varian instruments. We
have tried both HP LJ-1150 and LJ-2300 and
neither acknowledged receiving data signal at
all, whereas old printers (such as LJ-3 and LJ-
6) have no problems. I was puzzled because I
know others in the department have used LJ2100
for the same purpose.
It turns out the 2300 works perfectly with two
other Sun computers here: one is ultra-5 with
Solaris 7 and the other is sparc5 with Solaris
6. My instruments are all Solaris 8 on Ultra-1,
Ultra-2, and Sparc-5.
While trouble-shooting the LJ1150, I talked with
a technician in HP and was told that that all
new generation of high-speed LaserJet uses noise
filters and required stronger signal. With the
2300 you are supposed to be able to turn off
high speed printing. I did that and that did
not seem to make a difference.
Has anyone had similar problems? Is there a get-
around to this problem? Can I buy laserjet
printers from other manufacturors and be sure
that they will work? I am tired of buying new
printers and returning them.
