4. reinstall the formatter - phisical connection may be not good ( formater is a "cage" that the networc card is inserted)
go to http://www.hp.com for more information

there is nothing wrong with your printer!! it is a connunication issue from the computer to the printer... cancel the document that you tried printing and try reprinting it again.. to clear the error remove the USB cable or Network cable then turn off the printer.. then back ON while the printer is in the ready state re attache the USB or Network cable and reprint the document :-)

ISSUE: A 49.x service error appears on the HP Color LaserJet 4500 or 4550 printers display, and other unexpected errors may be displayed such as:

1. Turn the printer off, and then turn it on again. If the 49 error clears, proceed to Step 9.
2. If the 49 error returns turn the power off, unplug the power cable, disconnect all network cables, and remove the HP Jetdirect card, which is located on the formatter, (see Figure 1 for location), or any third-party devices, if installed.
3. Wait at least 30 seconds before plugging the printer back in directly to a wall outlet. Do not plug the printer into a power strip or a surge protector.
4. Turn the printer on, using a cold reset. If the 49 error returns, turn the power off, and unplug the printer. Remove the formatter, and check that the parallel I/O board is firmly installed on the formatter board.
   NOTE: To perform a cold reset, turn the printer off, and hold down the GO button while turning the printer back on. Remember to remove the Jetdirect card (if installed) before performing a cold reset. (The Jetdirect card is located on the formatter).
