I have had a recurring problem with trying to upgrade an HP III with an HP 4. The problem I have is with the one DOS software package (accounting program). The software does not have any printer setup features to recognize different printers so far as I know. The program is configured to work with an HP II or HP III. I have set up the HP 4 with the same lines, pitch, symbol set etc. but when cheques are printed the HP 4 doesn't align properly. I have always thought that an HP 4 will work using the HP III driver with no problems but I have not been able to find a solution to this.

Does anyone have any suggestions, ideas?
The software is called Macola. In my opinion it's a piece of junk but the client isn't about to change their system just because of my opinion.
