You might already know about alternate mode. This is epson emulation mode. 
It is controlled by switch 5 (up=Alternate). To select the IBM character
set, switches 6, 7, 8 should be up, up, down. 

There ARE differences. The thinkjet vertical resolution is 1/96; epson is
1/72. The aspect ratio in single density graphics is square on the thinkjet,
but not on the epson. Horizontal dot density is also different. 
These details can be found in appendix A of the reference section of the
thinkjet owner's manual, or at least the one I dug up (02225-90080).

Whether or not these differences mess you up is application dependent.


disclaimer: I don't work in the division responsible for the thinkjet,
and I simply did a (hopefully) informed transcription of the thinkjet
manual. HP is not responsible for what I've typed...But you knew that.
