The LP25's were Dataproducts Band printers... the serious fun was the
LP04, LP05, LP06, and LP10 drums. The band printers were very reliable
(LP25=300 lpm, LP26=600 lpm). Dataproducts called them the B300 and B600
band printers. The big band printer was the LP27 which was about 1000-1200
lpm.

with the LP06, LP2x stuff.

I was in my local Honda dealership the other day and they were using
old-assed DEC line-printers on their PC network (don't know which model).
I asked the guy about them and he basically said that yeah, they're as old
as the hills. But one started printing my invoice and I realized why they
kept them...they are FAST.

Were they DOT MATRIX? I'll bet they're not big old noisy line printers unless
they're sound covered and about 4 feet tall.
The DEC dot matrix stuff (except for the Printronix based P300 stuff that
DEC rebadged) were the greatest console printers ever built. I'd love
to put an LA120 on my PC here running FreeBSD. Unix begs for a real
ASCII tty console.

Yes they were dot matrix. I always equated line printers with dot matrix
printers. Is there a difference?

Just slightly :^) The line printers I'm most familiar with were about 6
feet wide, 3 feet deep, 5 or 6 feet high, in a sound proof enclosure, and
were impact printers.
IIRC the biggest I worked on was an impact printer with each character a
single link in a belt that made up a long loop. There were multiple
instances of the same character in the belt, and it whirled around real
fast, with a hammer behind it ramming it into the roll of inked fabric
(messy stuff). It could to single or multipart paper. The paper sat in
the bottom of the printer, and then the printer pulled it up and shot it
out the back into a stacker.
I somehow doubt it's possible for a dot matrix to even come close to the
speed of a good line printer.

And then there was the 'Talley' line printer.
A whole 132 charactior worth of a 'single dot'/charactor position metal
'comb'. The 'dot position' within the 'charactor cell' was
determined by
this 'comb' of 'dots' moving back and forth sideways (With a selenoid
foring at the proper time [one solenoid at each charactor position.)
With the verticle scanning of the charactor area accomplished by the
paper tractor moving the paper one 'dots' worth at a time. This ment 77
impacts per charactor (for a 7x11 dot matrix) But that was also 77
impact times for the whole line, because ALL the dots that were lined up
properly fired at the same time.
Heavy!!! 200+ lbs. for a 132 col (17"?/19"?) 'desk top' printer.
This is all from memory. It got sold before I left Calif. 18 years ago.

Is that one of the printers that holds an entire box of wide format paper,
and is about 3x6x6 feet in size? I used to work with a couple Honeywell
Printers that size, and I know DEC made a simular model.
On the Honeywell printers, you dreaded a paper jam, especially if you
didn't catch it immediatly. It could pile up half a box of paper in the
top of the printer enclosure before you could get it stopped.
Then there were the "Paper Parties" that the day shift had, where we had to
haul 20-40 boxes of paper out to the computer room and stack it in a large
pile. Thankfully I usually worked the Evening and Midnight shifts, due to
personal preference. These "Paper Parties" were tame to the smaller ones
on the Aircraft Carrier I was on, there you had to climb up and down the
ladders with these large boxes of paper, and carry them over half the
length of the ship.
