during print, power down your HP Deskjet and then cancel the print queue in the print manager settings. wait for the queue to disappear before powering on your printer. i do the same thing with my deskjet 710c.

are you powering up with your battery alone, or are you plugged into an outlet?\n\nhow old is your computer? is it worth spending money to fix it by going to a computer repair shop?  are your files very valuable?

There has been a minor issue with a few of the K550 printers. Some customers, even when they purchase a new black cartridge, are no longer able to print black. This is due to the printhead and cannot be fixed by purchasing new cartridges.\n\nGo to HP's website and e-mail them the trouble you are having and what you have done to try to fix it. They have an one-hour e-mail response team trained to help with questions such as this. You also have the option of calling their toll-free number which is listed on their website. And last of all, if you wish, they have free online chat with a tech.\n\nThere is someway to reset the printer to allow it to print in black. HP will walk you through this. If it doesn't work, they will likely send you a repair kit. Your printer is probably still under warranty, so this shouldn't cost you anything. Hope everything works out!

Check the power supply cable (the one with the 4 pins).  It sounds like it just isn't getting any power.  Even if there's something wrong with the jumper settings or the I/O interface, it should at least spin up.

Below is a link for troubleshooting your printer.  You may need to update the drivers.

Time for a new printer maybe.\n\nIf there is no power to the printer then its either the printer, the power cable or the socket.\n\nolder printers often have a power switch on the back- check that.\n\nPlug it into a different power socket and see.\n\nTry another power cable and see.\n\nBasically if its the cable or the printer you may as well buy a new printer as a replacement cable can be expensive.

You have a few options. But first ensure that you have all the ink tanks installed properly.\n\n1) If you just purchased it take it back to the place u bought it and have them replace it.\n\n2) Search HPs website for a FAQ for the psc 1400\n\n3) Call HP tech support and have them walk through diagnostic steps with you.

lift the hood and see if its there, if not try the documentation that came with the printer. if you don't have one , go to HP and click on support. there should be an on line manual that will show you.

I suspect your Print Head might be faulty. The first link below is the HP site for your Printer. The second takes to troubleshooting and diagnostics. The last is the manual.\nCheers and Goodluck, a print head is very expensive and usually its cheaper to buy a new printer.

what make and model of printer do you have ? If it is a hp then there should be some extra software that came with it that should let you configure how it prints off the pages etc.

Can you print a demo page from the printer? That is always the best first step in diagnosing a printer problem! If you can, you know the printer will print, so we can move on to the connections.\n\nEnsure your connections are sound. Unplug and reattatch all your cables, including your power cable. (If you can't shut off your Printer using its own power button, that may signal that there is a serious problem with the printer.) OK, once all the cables are back in place, try to print again. NOTHING?\n\nNext, uninstall and reinstall your printer. Ensure that you completly uninstall your printer from your PC, don't just update the drivers. The installed drivers may be corrupt. Also, if you allow windows to reinstall the drivers and the printer continues to have the same issue, you may need to download a new driver from the manufacturers web site. If the windows version of the driver didn't work, uninstall and reinstall using this downloaded driver instead.\n\nIf that doesn't work...here is where can get pricey!\n\nFirst, if you have a friend with a accessable PC, take your printer there, hook it up as you would at home and see what happens. If it has the same issue there, then you have narrowed down the problem to being either the printer or the cable connecting the printer to the PC.\n\nSecond step would be to replace the printer cable. (Mind you, this may not be your issue, it could still be the printer and you may waste your money) A good solution is if that same friend uses the same type of cable you do, use that one and see if your printer works. If none of that works, it is time to put that printer out to pasture and buy a new one!

The roller-grabby thing keep grabbing two sheets of paper and then jams up.  To make matters worse, it makes a beeping noise.  When I take the paper out and try to print again, the madness starts all over.\n\nThe good folks a Hewlett Packard have my thanks.

not sure what kind of printer you have, but some printers have a refresh button, try that.

Maybe the circuitry is fried.  Reinstall the printer driver, make sure none of the plastic strips are still in the printer cartridge and then reboot your computer.

depends on the brand it is . i have a hp, and i have to go to "my printers and faxes" under my computer and cancel all print jobs,then go to settings and change the way the power options are. sometimes you can unplug the printers power for 15 seconds to clear the memory good luck-- hope this helps
