Well, the CGP-220 looks suspiciously like a Quadram Quadjet. But I
rather doubt they are compatible at the level you need (but I'd bet
the ink cartridges are interchangeable!)

The problem is best described by reffering to my DMP-2100. This printer is 
for all practical purposes, a Toshiba (p-351?) with A DIFFERENT SET OF ROMS!
The ROMs are the problem. Tandy printers without IBM emulation modes are
essentially useless for graphics except with software that supports Tandy
grapics. 

I do have a couple of programs that will let you use an older Tandy printer
with the version of PrintShop that supports the newer Tandy printers. (No 
program would be necessary if they hadn't "kludged" the Tandy support. PS
Goes into graphics mode, prints a line of graphics, goes *out* of graphics
mode, sends codes to do the right kind of partial linefeed (which aren't
valid for older Tandy printers like my DMP-500), goes back into graphics
mode, prints another line of graphics, etc... all they *really* needed to do
is go into graphics mode, send a line of graphics data, do a CR/LF, send
the next line of data... and then exit graphics mode at the end of the printout.. <sigh>
