The Cartridges for the HP DeskJet 3740 InkJet Printer are:

HP 28 Tri-color Original Ink Cartridge

These can be purchased from your local store that sells HP Printers & ink or by going to HP.com and ordereing direct from the Manufacturer

Run a few "print-head-cleaning" cycles, to get the black ink flowing through the ink-jets inside the print-head.

Some printers REQUIRE an "alignment" step every time you change the ink-cartridges.
It only takes a few minutes, and it prints one or two pages of paper.

Open up All printers and faxes by right clicking the printer icon in the system tray.On the maintenence tab check your black ink.Check to se if the tape is stil on the carftridge. If it is remove it. Printer should print black ink once the tape is removed.If it is removed. Try changing your black ink for a new one. Also sometimes your ink may not be compatible. Make sure you use compatible ink

In my case this happened with black cartridge out of ink, colour cartridge low; replaced black: had permanent alignment problem, though test print looked OK; wouldn't print black. Replaced colour cartridge, then it all worked OK, straightaway!

check your printer settings (properties) to see whether it says "pause printing" or "offline"

nope, there should be no tape on the cartridge. This is preventing the ink from coming out.

Does the printer attempt to print? Did you replace the black or colored ink? If it was the black ink will it print in color?
If it prints in color, check the black ink cartridge for tape residue on the gold contacts. The blue tape will sometimes leave the adhesive on the cartridge and not the tape. It cleans off easy with a soft cloth.

As suggested a couple of minutes ago, with a fresh cartridge installed, disconnect power (unplug) and let the unit rest for an hour or so and then reconnect it.
This may clear an internal error register.
