I have a question about the Atari ST screen-dump (which can be invoked by typing ALT & HELP at the same time. My question is this: Does this screen dump work with non EPSON compatible printers? If so, which ones (and how can it tell what kind of printer is connected)? Thanks in advance, Eric Terrell (att!druhi!terrell)

And by the way, the reason you're getting 3/4ths of the screen is probably not due to 80 columns, but because the ST thinks you have 1250 dots across. Try using the Control Panel to "Set Printer" to 960 dots, and see if that improves the situation. --R.J.

The ST sends a command (ESC 1) which sets 7/72 inch line spacing. As 24-pin printers spacing are only 1/60 inch spacing, they do not reco- gnize this command and so you can't dump screen on them. Naturally, only experience can tell you this fact (-(- The needed printer codes are: esc L (graphic data), esc 3 (1/216 spacing), esc 1 (1/72 spacing). ----- Bertrand DECOUTY @ INRIA-IRISA (Centre de Rennes) ----- +------------------------------+----------------------------------------------+ | IRISA - INRIA | EMAIL : decouty@irisa.fr | | Campus de Beaulieu | | | F-35042 Rennes Cedex | UUCP : {uunet,mcvax,inria}!irisa!decouty | | FRANCE | decouty@irisa.UUCP | +--------------------------+---+--------------------+-------------------------+ | PHONE : +33 99 36 20 00 | TELEX : 950473 UNIRISA | FAX : +33 99 38 38 32 | +--------------------------+------------------------+-------------------------+

Presumably terminate-and-stay-resident, but how does it intercept keypresses? A couple of years ago Moshe Braner (where's he gone?) posted a program which did this but it shoved the screen into a reserved area of memory he called the "barrel"; then you could dump the barrel to a Degas file. I'd like to try writing a program which instead created a .TNY format screen file every time alt-help was hit.

What sort of printer do you have that isn't Epson Compatible? From what I understand almost all printers have available an Epson : compatible mode. Some of the others are Epson compatible but the dump doesn't work properly for one reason or another. There are PD programs around which allows the use of the Degas style of printer drivers to replace the standard. Also there is a program for the 24 pin printers which definitely works for the Star NX2400 printer which gives excellent printer dumps. I still have a friend looking for a printer driver for GDOS which will give better definition for the Star. He has been told of a driver in the PD which will work for GDOS for the Nec P6/P7 printers which should work for the Star. Has anyone seen these available for download anywhere? > The screen dump works fine on my Panasonic 1091i, although I only get > 3/4 of the screen since it's an 80 column printer. As far as I know, > the screen dump should work with any IBM compatible dot matrix printer. There is a modification you can make yourself using your control panel and then save in the DESKTOP.INF file. One of the settings for the printer 960 or 1280 bits/pixels per line. Set the printer for the 960 and you should be able to see the entire screen dumped. Hope that helps. -- ******************************************************************************* * euloth@dalcsug.uucp || Disclaimer: All opinions are my own unless other- * * /\/\/\/\/\/\/\/\/\/\ || wise noted. * ****AKA: Atari Nut*************************************************************

Once you've got contrl there, you should be able to do anything with the screen... Don't know about the specifics (use Kbdvbase() to grab the system keyboard vector, that's about all I know), sorry. --Kenneth Soohoo (soohoo@cory.Berkeley.Edu) Atari 400/800/600xl/800xl/1200/130xe/65xe/xe game/7800, 1040ST/MEGA hacker "It could be worse, you could get hit by a truck..."

All you need to do is take over that vector, whenever the user presses Alt-HELP your code will be run. Check the "Hitch Hiker's Guide to the BIOS", it has the official list of low memory vectors and variables. Dan Moore AT&T Bell Labs Denver dlm@druwy.ATT.COM dlm@druhi.ATT.COM
