So I've performed all the required/documented steps, just like I've successfully done in the past for other clients, but still it keeps printing as if the stock is 11"" long. This is an Oki 320. The only one thing I know I haven't done is specifically use 'IBM Proprinter' as the driver, but I did try a number of other ones incl ""Generic/Text"" - and I don't quite recall using 'IBM Proprinter' in the past, but it's certainly possible I have. Should I really try the IBM Pro? Any thoughts besides just suggesting the client suck up the cost of not being able to use up their 8.5"" x 7"" dot-matrix pin-fed Check stock?
