VFP6: Getting Lousy Output -

I have a dot-matrix printer that I use for Q&D output. When I print from DOS programs, it works great and spits out the output quickly. When I print from VFP (or any other Windows app), it insists on making it better quality. This takes several times longer. How do I set the printer driver to give me low-quality (and fast) output? Sincerely, Gene Wirchenko |

As I am in France, I had a problem with this driver : I had to use CPCONVERT() to get all french special characters. The Generic Text driver doesn't translate the codepages. That is, what this driver is for: do nothing with the print data, just transfer |
bytes to the printer and the printer builds letters from these bytes, exactly as
it was in the old dos days. A lot of printers are ascii text printers and the
ascii code page is different from standard windows code pages.

exactly as it was in the old dos days should have been "exactly as it was in the GOOD old Dos days" ;-)) |
As I am 'old' (51) I did spend a lot of time on DOS !!

Hi Jean As I am in France, I had a problem with this driver : I had to use CPCONVERT() to get all french special characters. The Generic Text driver doesn't translate the codepages. That is, what this driver is for: do nothing with the print data, just transfer it 1:1 from the application to the printer. So the application simply sends some bytes to the printer and the printer builds letters from these bytes, exactly as it was in the old dos days. A lot of printers are ascii text printers and the ascii code page is different from standard windows code pages. Regards Bernhard Sander |

Set up a separate printer using that driver and use that for your reports. |
Unfortunately, it is only 10 CPI. I switch between 10 and 12 CPI
(or some close approximation) with set printer font. Those do not
work. I tried setting them up in the driver, and the resulting output
was garbage. Oh, well. Odd that the DOS window has no problem
working the way I want.

Thank you. I did that and now get the fast output. Unfortunately, it is only 10 CPI. I switch between 10 and 12 CPI (or some close approximation) with set printer font. Those do not work. I tried setting them up in the driver, and the resulting output was garbage. Oh, well. Odd that the DOS window has no problem working the way I want. Imagine it maybe like this: |
the new font. Since Generic Text has no fonts built in and does not know what
printer is connected and also does not ask the printer what to do, then it
consequently does not add any control sequences into the data stream to the
printer. It is a purely pass thru driver.
Here it is up to you and your program to add the right control sequences in the
right moment. Just like in "good old DOS times".
