print command on Apple GS

[dave <spammers@really.suck>]

Hi

I guess this question is kind of pre-this-group, but it's likely that
someone out there knows the answer.  Love to hear from you if so. 
Please copy to my email: graves(AT)cs.ubc.ca

Here is the predicament:

Old Apple GS
Running under DOS 3.3
Image-Writer I with a cable that seems to connect them
Can't remember command to print

Thanks a lot,
Dave.
