I apologize for adding something here about a question I asked in October 2020, but at the time I was real busy and since the reports were for internal use, I did nothing. Now I have time, and the same error still exists.
It is not about the double line. That works in “REPORT.” It’s the single line which “c4” is supposed to create, but doesn’t. I’ve changed the setup line with several printer configurations, but no single line. The REPORT I can print (I use printfil) that is nice and clean, but without the single lines is configured this way.
Printer Options: PRCPRN
REPORT Printer: HP10P
Need more suggestions.
