EPSON TM88 Thermal printers: How do I download images (logo)

Archived from groups: comp.periphs.printers (More info?)

We are using Epson TM88 thermal printers linked via HP JetDirects to a
Unix environment.

We want to download a logo to these TM88 printers, and print POS
receipts with the logo on the receipt.

I'm quite 'au fait' with downloading PCL images (macros/overlays) to
HP-Laserprinters via the network to a TCP/IP-address, but how do I do
same to the Epson TM88?
Are ther any software available to do this?

Any help/answers/pointers? Please mail me direct @ my email:
syht@sun.ac.za just revserse my name to read 'thys'
