- Necscrn.com is a graphics and text screen dump program that
- should be run ONCE after powering-up. It will attach itself to
- the operating system, and then will operate by intercepting
- Shift-PrtSc keystrokes and invoking the appropriate routine to
- provide either a graphics or a text screen dump, depending upon
- the current mode of the system, on an
-
- ************* NEC 8023A Dot Matrix Printer *********************
-
- The graphics dump comes in two flavors, either a small (one dot
- per pixel) or a large (4 dots per pixel, with the dot pattern
- roughly corresponding to the color) format, depending upon
- whether the left (large) or right (small) shift key is used.
- For the small graphics dump, the aspect ratio is fairly accurate
- when the printer is set for 10 characters per inch (the normal
- power up default mode for the printer). The large graphics dump
- prints out rotated 90 degrees on the paper, and the aspect ratio
- won't be right (circles will look elliptical..) unless the
- printer is set for 8.5 characters per inch. This is done by
- selecting the 17 character per inch character set and enlarged
- characters. A one line basic program that will do this is:
-
- LPRINT CHR$(14);CHR$(27);"Q";
-
- This program is a patched-up version of the GRAFTRAX.COM
- program supplied on the Capital PC Users Group Diskette #5.
- It will probably work with the C.Itoh ProWriter printers, since
- they seem to differ from the NEC only in their packaging (and
- in other minor details such as 20% faster printing, an improved
- proportional character set, and a re-shuffling of the greek
- alphabet to put it into (greek) alphabetical order). I would
- appreciate hearing from anyone who knows how to modify the ROMs
- on the NEC to incorporate any or all of these features.....
