I'm using an old DOS program for editing operator interface terminal. in the DOS box the video is folded over. I have attached a jpeg of what the screen looks like. I'm running it on an IBM Thinkpad A20, Win98. The part of the jpeg that says NO File, belongs in the upper Left corner. I tried changing different video options in the conf file

Thanks for any help.

Could you tell what version of DosBox this program did NOT work in?

You see the version of DosBox that vasyl linked to contains unofficial patches that may not be in the official CVS.....so we need to determine if the problem is fixed in straight CVS or in the patches.

So if you could, could you click on the "Unofficial CVS BUILDS" in my signature. Surf down to the "AEP" CVS link, download that and place it into the same directory as the dosbox you already downloaded. Then execute it and try your program.

If your program works then that means that when the next official version of DosBox comes out that your program will still probably work.

Hi Dosfreak,
Yes the build dated 10-16 did work and I'm now using that. If I try to print from inside the DOSBox, is there a way to capture it to a file? The biggest file capture comes out to @ a 400K text file. So standard DOS capture programs don't normally work. Really quick reponses in this forum. Thanks

Thanks
George

DosBox does not and will not (well never say never...) support printing.

BUT

The unofficial builds of DosBox like the one Vasyl linked to do support printing. So if you use that one then you should be able to print. The only catch is that you will not be able to print to your printer directly. Your program will print as it normally does but DosBox will output it to a .png file from which you can print to your printer.

There is also some print option to actually invoke Windows printing dialog. No direct printer passthrough yet.

IMHO, that's better solution anyway. In DOS days a program had to support particular printer model to print anything besides plain text in fixed font. There were a few widely supported "standards" (ESC/P, PCL) but even those required some per-printer configuration. Throwing all that data directly to printer port of modern computer is not very likely to work. Some HP printers may still recognize PCL and do something reasonable but I would be very surprised if my Canon PIXMA accepted command to upload glyph in ESC/P mode. I do have old skool system but I am not that old skool to put Epson 24-pin monster on my desk 😉

The point of using a direct passthrough method would be printing from a ms-dos application exactly the same way you did it under real ms-dos, totally bypassing windows printing engine. I look forward to this. I've been trying WordPerfect 6.0 for DOS under DOSBox and works great. And of course you would still needing a functional ms-dos printer driver to do it (in most cases).

Thanks for the responces. Since it is now working and doing what I origionally started out to get it to do, should this be a new topic in a different forum? I tried printing and the Oct build prints each page as a seperate .ps file. How do you get it to just keep appending to one file ( I prefer it stay as a file that I can send to Word and clean it up).

Thanks
George

Hopefully one last question still related to same software running in DOSBox. Out of 15 different screens I can switch to, they all work except one. I get an error: Exit to error: Pagefault didn't correct page

when I try loading this one screen. For the most part not a lot of difference in the screens. What does this error mean? It may explain what it is doing.

Again, I know it isn't a game, but in older industries we can't just get the newest of everything that comes out. This looks like it may get some of us out of trying to keep old 286/386 notebooks alive. Which is getting harder all the time.

Any ideas?
Thanks
George

Yes, even though it is old, I don't dare give it out. I'm attaching a word Document of the offending screen along with a similar screen that doesn't crash it.

Thanks

Try the full core and play with the ems/xms/memsize parameters
in dosbox.conf, might help.

Thanks for the continuing help. I tried what you suggested, still shut DOSBox down. Today I tried in full screen mode, and the first thing it did, is to go into a DOS window, then shut down. Does this give you any more ideas to try?

Thanks
George
