Answer» Hello! I from Russia.
Allow to ask a question please.
I quote from the textbook:
There are the combinations of keys processed in special way:
... PrtScr (or Shift PrtScr) - the press on the printer of a copy of the contained screen in DOS...
On the computer it is established MS DOS 6.22. The printer is absent, but there is a question.
When I start FILE Print.exe, it is visible that the system is ready to work. The system requests page which should be unpacked.
At attempt to take advantage of the function described above, the system does not react. I think, that if to connect the printer - too NOTHING will occur.
Any files of system need to be edited?
There can be this function is an external command and consequently the additional program is necessary?
I ask to answer please with an official language as I badly know English.
Under command-line based operating systems such as MS-DOS, the PrtScrn key causes the contents of the current text mode screen memory buffer to be copied to the standard printer port, usually LPT1. In a GUI operating system such as Windows, a bitmage image of the screen is copied to the clipboard.
Whether the system should report at use of this function?
Or she SENDS the image on LPT on-default?

If printer is connected and switched on and has paper it will immediately print 25 or 43 or 50 lines of text (the text screen contents)Thank you very much. I Will search for the corresponding printer.The computer will freeze until the printing is finished.
