I am working on a project that requires me to use a VB.Net forms application to save a PDF and from there print that file to my impact printer. That's the easy part.
The printer that I'm using is an Okidata Microline 321 Turbo. That uses a Generic IBM Graphics 9pin wide driver.
I have been able to print the form, however the font makes the words barely readable. I've been doing some research and tried changing the Default CPI from 10 to 20 and that did not help. I was wondering if the answer lies within the driver that I'm using. I've tried several drivers but the Generic IBM driver seems to work the best.
Is there a setting that I would need to change either on the printer or the printer properties to get the font to print more clearly?
The text size cannot change however the font type can be. I believe that the issue goes beyond the font size but I wanted to rule it out.
Failed Fonts:
Arial
Consolas
Courrier New
Tahoma
Verdana
Thank you in advance for any help that you can provide.
