Does the same thing happen if you plug the computer into a different circuit? (Temporarily use an extension cord if needed, of adequate size of course).

Doc, I just noticed your post #14. I apparently failed to see it when I replied to bruce b post #13 as represented by my post #15.
The answer to your question is no I do not use a strip to power my
HL-2040 printer. And now, the printer is plugged into it's own wall plug. If ever I don't have a wall plug available, I have used my APS backup battery for the power, which also serves as the power for my computer and monitor. And the APS is plugged into it's own wall plug.
I had the same problem with the HL-2140 new out of the box.
It printed the first time, then would shut down the computer when ever I tried to print or even if I tried to do a firmware update, or even just turning the printer on.
I fixed the problem by plugging the printer into a completely different circuit with and heavy duty extension cord.
buf - I just saw your last post. roddakota is correct, your printer should never be plugged into your UPS. In many cases, you will actually need to plug it into a different circuit than the one the UPS and other computer equipment is using. I have had this happen in a number of installations. Larger laser printers, especially color ones, draw a lot of current.
One example ...
HP Color LaserJet 2800 All-in-One series

I accept your input good people and will put it into practice as soon as I physically can. I have to add though, I have always used the UPS and never before had the problem. Always the first time, however.

...
Note: In order to ensure longer runtime on a battery, laser printers should never be plugged into battery backup outlets of a UPS. Be sure to use the “surge-only” outlets (on appropriate models) for laser printers. For those UPSs without “surge-only” outlets, it is recommended that the laser printer be plugged into a separate APC SurgeArrest surge suppressor.

QuestionWhat is the proper UPS for use with a Laser Printer?AnswerDue to the large amount of power consumed by these devices, APC does not recommend protecting laser printers with a UPS.
In most cases, surge protection is adequate for laser printers.
If you must use a UPS with a Laser Printer it is important to size your UPS appropriately. APC recommends a Smart-UPS series product that is sized for the maximum power draw of the laser printer as defined by the manufacturer. This is typically a 1500va or larger UPS. Even small laser printers can have very high maximum power draws due to the nature of the technology. We do not recommend the use of Back-UPS products with a laser printer.
Many thanks for going the "extra mile" Doc with your links and info. I should be able to take care of this problem with the HL2040 AND HL2140. Well as soon as I can physically take care it.
My printer problems are now resolved, thanks to you folks. I have each of the two printers plugged into "their" separate wall plugins.
Great hear the problem's been solved. Thanks for posting back. :)
