I've reset hard, cold, nvram... changed cartridges, drum... Nothing helps. Printer works but no ready light and no flashing ready light during receiving data (printing). BUT the ready comes on during the various flashing init cycles.
I've had this fault myself, If memory serves me right the control panel ( small though it is) we found to be the problem, once replaced the unit the displayed correctly, weirdly all functions of the printer were still available even though we were unable to see the display.
we were able to get config pages etc, and like you say the indicator lights were working- sort of - when they wanted to.
replace the diplay PWB ( its small and reasonably cheap)
SOURCE: "Printing" but nothing comes out......
Hey dear you did not describe the full detail. Light is continuously blinking and nothing is coming out from the printer OR printer is not printing anything. If the printer is not printing anyting and light continuously blinking. It means printer is not properly getting the data. You have to change the 'encoder' (a transparent strip goes through the carriage) and you have to clear the round transparent encoder present left side in the mechanical with wet cotton. After this your printer will work smoothly.
SOURCE: won't print after changing print cartridge, check printer cartridge light comes on!
please install the printer hp 1200 series

Routine maintenance and keeping full ink tanks will prevent this problem, however if you have the problem you can resolve it by doing the following:
1. Clean your print head using denatured alcohol solvent which can be purchased from most hardware stores. If unavailable, use 91% Alcohol (isopropyl alcohol (first aid antiseptic) which is available for less than a dollar at most Walmart pharmacy departments.
*Warning: You may want to use a pair of latex exam gloves as this is a messy process and can stain your fingers.
Time necessary 45-50 minutes
Supplies needed:
Isopropyl Alcohol or denatured alcohol
paper towels
latex gloves
sink, bowls and or basin
can of compressed air
very small screw driver
tablespoon or baby bulb type syringe
warm water
PROCEDURE:
1. Lift print head from printer. It pulls out easily because it is held in with the same down lever that holds the cartridge in place.
2. Put two layers of paper towels in the bottom of a dish to protect sensitive sprayer heads.
3.Put enough solvent in dish to cover the screens on which the cartridges sit when in use.
4. Take the two small screws out that hold the white ceramic piece
5. Gently, pry the ceramic piece back and away , to reveal the underside (No need to pull away the glued points on the sides.)
6. Gently, move head up and down to slosh solvent around it the best as you can. Use a table spoon or syringe to pour solvent over all orifices in the print head, turning it upside down and then back a few times.
7. Use canned air with a plastic straw to blow into and through all orifices, alternately sloshing/swishing and pouring solvent over head (be careful not to touch any of the holes, screens, or sprayer heads with anything)
8. Empty dirty solvent from bowl and replace with paper towels and clean solvent. Soak for approx 10 minutes. Rinse again with clean solvent poured directly on all parts, letting solvent overrun and fall into dish or basin.
9. Gently shake the solvent off the head, take it outside and spray with compressed air into all orifices to clear out and help evaporate any remaining solvent. Let sit on a clean paper towel for approx 20 minutes. (There may be a little ink bleeding out of the head, but once it dries completely it does not present any problems.
10. Reinstall head, cartridges and it will print like a new printer.
SUGGESTION: For many years of problem free printing, keep a double set of ink cartridges, one set full at all times. Whenever a cartridge runs out of ink, replace it IMMEDIATELY, with a new one or a refilled one. This gives the print head no chance to dry out and create clogged heads. Routine maintenance of cleaning the heads every 24 months does wonders for keeping your printer in new condition.
Hope this helps. .

HI,
This a formatter failure, sounds like the formatter went out while trying to do a hard reset or after updating the firmware,
Try doing a nvram:
Turn the printer off and hold the down arrow and the cancel button
Turn the printer on while holding the two buttons down
Continue holding until you see the permanent storage message and wait for the ready message to display
If this doesn't work call hp and tell them that printer is frozen and will not initialize, this is due to a formatter failure. If it has been less than 2 years since the purchase date then you will apply for a service note and will be able to have the printer serviced for free, Contact hp's tech support at 1800-334-5144.
