Artyman, ZZZEnDog's suggestion is a good one - if it won't turn off, just power it off at the wall. Also, I found these two comments on a printer forum:
On the "Epson Stylus Photo 2100/2200 series", if the "Power Light" is off and the "Paper Light" and "Ink Lights 1 thru 7" are all on a HIGH SPEED BLINK [ high speed blink equals a 0.1 sec's on + 0.1 sec's off repetition], that actually indicates a FATAL ERROR service condition. If all 8 lights are actually doing that high speed blink at the same time, then your printer is actually in that fatal error service condition. The fatal error, usually inducates a problem in either the carriage assembly, a home position location problem, or a paper feed motor problem. There's no way for me to know what is wrong with your printer, but the two most common problems are a DIRTY and or DRY "Carriage Assembly", or a DIRTY "Encoder Strip/Sensor Strip". You may want to clean and service those two areas [if your printer is actually in that fatal error condition], just to eliminate those common problems..
On the other hand, if the power light is off and the paper light is blinking alternatly with ink lights 1-7, rather than all 8 lights blinking at the same time [as in the high speed blink pattern], that would indicate a MAINTENANCE REQUEST ERROR. The maintenance request error is actually a "Waste Ink Ink Pad Error" and usually your remedy is to replace the waste ink pad/pads with a new one/ones and then reset the "Internal Waste Ink Pad Counter". If you just reset the counter and don't replace the pads, then your printers old pads will eventually overflow and normally start leaking ink out the bottom of your printer. You can see exploded parts diagrams for most epson ink jet printers and can also check on possible parts ordering, by Compass Micro Inc, at
http://www.compassmicro.com/parts_select.cfm . Some people actually wash the ink out of the old pads, by holding them under running cold water. Then they simply dry them out and reinstall them back into their printer. The choice on what to actually do, is yours to make

but it sounds to me that your venerable old Epson printer is ready for the retirement home. I've used Epson printers myself for many years and I swear by them. They've never given me an ounce of trouble, but I've never had one this old either.
