Hello & Welcome to Just Answer,
Sorry to hear of the issue you are having with your printer.
Unfortunately, this particular printer does NOT support SDHC Memory cards. I suspect this is because of the AGE and design of the device - at the time it was manufactured.
If you can still find an older SD card (that is NOT "HC" - High Capacity), then that should be supported - up to 1GB in capacity.
I did a search on Amazon for "1GB SD card" and have the search results below.

You can see ALL the specification of this printer (including "Input/output" specifications) at the following link.
I hope this helps explain this issue. Please let me know if you have any more questions about this device.
