Question about Zebra LP 2844 Thermal Printer
I bought a Zebra LP2844 printer from someone on Ebay over a year ago. I ended up not needing it right away so I didn't install it.
Now, I'd like to use it and it just doesn't power up at all. No light at the feed button.
I noticed that the input for it is listed as 20VDC 2.5.
Here's the rub, though. The seller shipped an 808061-001 Eltron power supply. That supply is 16VAC 4A.
So, assuming this printer was working when I got it, what is the likelihood of the printer still being able to function if I get myself a 20VDC power supply after having a 16VAC one plugged into it? Will the higher amperage or the fact that it was AC instead of DC have blown any chance of this thing working?
Is there any way of testing it? I'm beginning to think I should have a general power supply that I can plug things into and change the voltage on it to check things like this. I would have to know how to figure out which wire on one of these round power adapters gets the +/-.
What I learned.
the printers being sold as LP 2844 all over the place is actually an LP 2543. It was made for UPS, specifically, and they are being sold in large lots to refurbishers. It looks almost identical to the LP 2844.
LP2844: DC 20V 2.5A tip positive; all of them have USB ports!!
LP2543: AC 16V 4A; have only parallel and serial. Cover has a lighter shade to it. Most either have the label scratched off or a fake one put on.

If you plugged in a DC power supply to an AC device, yes this will cause damage. Most cases it will blow a fuse in the printer. AC - Alternating Current meaning it goes back and forth up and down. DC - Direct Current means it stays constant at this level. You may be able to get a proper power supply, change the fuse and all OK but doubts will always remain if the printer doesn't power up.
