NOTES ON PRINT.COM 1.01
──────────────────────────────────────────────────────────────────────────────
PRINT.COM is a simple file-printing utility. It doesn't work a great deal
differently than the DOS command COPY filename.exe PRN, though it does have
some simple enhancements. This utility is only useful with ASCII (text)
files.
SYSTEM REQUIREMENTS AND NOTES
You'll need about 65K to use PRINT.COM. If there are parts which are designed
to print on the screen in reversed (black on white) lettering, or in 40-column
mode, you'll also need CGA to see those. As I understand it, the computer
will just ignore commands for the preceding if you have MDA, but don't hold me
to that.
At this time, PRINT.COM can only print 80-column text files.
In some cases, there may be a bit of a problem with formatting. In general, I
would recommend against using this utility for a final draft. It is, however,
quite good at getting a general idea of how the finished product will look.
USING THE PROGRAM
To print a file just type PRINT [path]filename.ext at the DOS prompt, where
[path] is optional and indicates the path to your file, and filename.ext
indicates the name and extension of the file you want to print. Printing will
begin almost immediately. If your printer is not on, on-line, and loaded with
paper, you'll get a DOS error and be invited to Abort, Retry, Ignore, etc.
While printing, if something goes wrong with your printer, you can press the
space bar. This will stop printing from PRINT.COM; however, your printer has
a buffer which holds data to be printed. It will attempt to continue printing
until that data is exhausted. So, if you want to stop printing in real life,
press the space bar and then take your printer off-line. Pressing the space
bar first will allow you to continue printing after you've gotten the problem
straightened out. Otherwise, DOS may complain about the printer not being
ready, which could be a hassle. You can do the same thing if you get company
and don't want to have printer noise. To resume printing, press any key.
This feature probably isn't technically necessary, but I felt it was a bit
more elegant than generating a DOS error.
You can also abort printing by pressing the Esc key. Again, if there's data
in the buffer, your printer will continue to merrily bang away until it's
gone. If you want to empty the buffer, you'll have to turn off the machine,
wait at least five seconds, and then turn it back on. You'll need to adjust
your paper so that your next printing job doesn't start in the middle of the
page. If you can afford to wait for the buffer to clear, however, PRINT.COM
2
will send a form-feed signal to the printer, so that the paper will be
properly aligned when the buffer data has been printed.
PC-Write uses ASCII 12 and ASCII 15 to force a page break. Version 1.00 would
obediently send a form feed command to the printer, and then send a command to
print in condensed print, which is the ASCII 15 printer command. Version 1.01
now just forces a page break and does not send the printer into condensed
mode.
That about covers it. Your comments, criticisms, and questions are welcome.
Please use the phone number only if you can't get the program to work; any
suggestions and what-not can be sent at the address on the first page. I look
forward to hearing from you; I want to write the highest quality software I
possibly can, and I need your comments to help me do that. Thanks.
PRINT.COM was written with ASIC 3.01, an excellent shareware compiler by David
Visti. I highly recommend it. Mr. Visti can be reached at: P.O. Box 2952,
