I never published a book before so I'm unfamiliar with printer-author etiquette. After I receive quotes from printers, my requests to have samples mailed are ignored repeatedly. I don't think I should have to drive 6 hours round trip for samples of their craftsmanship (I live far from them). On the other hand, they are unsure of my motives and might think I won't return their property. My lack of publishing experience means that I don't know if I'm being unreasonable or if they are. Do I make the first commitment by having my designer hand in my manuscript file, or do they commit first by mailing me samples of a couple paper types and soft covers?
