I want to dissasemble my printer HP 842c for cleaning it.

SOURCE: HP Desk Jet 842C printer - need cable

Hi Debbie,

You should be able to use this printer with a USB cable. You can pick up a USB cable just about anywhere that they sell computer or printer equipment. Just tell them you need a USB printer cable. This is a standard item and no further description is needed.

The Driver for this will probably be a native driver, and you probably wont have to download a new one, but just in case, here is the link for the driver directly from HP.

Good Luck

Paper lift mechanism is broken. It's uneconomical to have repaired, sorry.

SOURCE: Is HP Printer #842C not usable with Windows 7?

To some degree they are correct. Your printer is NOT Windows 7 compatible. However that does not mean that some of the functions may not work. According to HP it can be made to partially work with W7. However for the price of new ink cartridges for this old printer which you may or may not ever get to work correctly, you can buy a brand new printer that will work with W7 and be superior to the printer you now have. From my experience with old printers this may very well be your best solution but it is your choice. I personally would just buy a new pinter. Here is what HP say's about this issue: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01874792&lc=en&dlc=pt&cc=pt&lang=pt&product=60426
