Hp HP LaserJet 1200

HP Business Inkjet 1200


I have been refilling the ink cartridges on the above printer HP Numbers 10 11 ect and I think they have reached expirary date so even if I refill them they still do not work is there a way around this problem without purchasing new cartridges as I can not afford to do this at present.

If anyone is still using one of these here is the simplest work-around to the expiration problem: Just before you print a document, simply change the date in the printing computer's "date/time" setting to a date earlier than the expiration date(s) on the problematic cartridge(s). The printer driver apparently supplies this date to the 1200 at the start of each print job. (No date is stored in the printer).

We have a 1200 networked in a small mixed Mac/Windows LAN, and this trick works for every system. It's a bit of pain, but if you just leave the time/date utility/control panel open on your desktop, it's not big deal. I just toggle the date back one year before I click "Print", than toggle it forward to right year after the job has been sent. It's actually very satisfying to foil HP's evil plan several times a day.

This might work on other HP Printers, though I haven't tried it. Worth giving it shot though.

Maybe can workaround similar to driver patch I used on my K850 printer? See http://www.fixyourownprinter.com/forums/inkjet/62052.
