I have an el cheapo grande Canon printer/copier/scanner that doesn't print things properly for one application program. The developer of the program refuses to answer questions about it (and I'm one of the "owners" of the program). Working from the other direction, I contacted Canon tech support via email to ask what kind(s) of printing input data their printer accepts (plain ASCII, Postscript, RTF, et al). They gave me an answer but it was ambiguous. When I asked for a clarification, I was told I was given all the info they could.
Is this typical of Canon (USA)?
