- PRINT TO DISK Utility, Operating instructions.
- Use with version 2.0+ MS DOS
-
-
- FUNCTION:
- This utility is designed to redirect the printer output from an application
- program to a disk file.
-
- There are three advantages to doing this:
-
- 1. Programs that required a printer may now be run without
- physical having a printer attached to the system.
-
- 2. Even if you have a printer, you may just want to look at a
- report without actualy needing a hard copy printout. In this
- case you can save the paper/ribbon expense and general wear
- and tear on the printer itself. Later you can print the file
- if you so desire.
-
- 3. There are times when only a portion of a long printout is needed,
- or you may wish to add information or comments, or incorporate
- all or part of a report in another document.
- You may now put the report into a file, edit it as desired,
- and then print the modified file.
-
-
- LIMITATIONS:
- There are a couple of situations where this utility will not work properly:
-
- 1. This program only traps the normal print vectors. This covers all
- normal MS DOS applications programs, BASIC programs, and most
- system type utilities. But, any program that works directly with
- the hardware output port will continual to function as it would
- without this utility.
-
-
- 2. This program changes the above mentioned vectors. So do all
- spoolers, printer drivers, and other utilities that affect printer
- output or operation. Therefore, this program MUST be the LAST
- utility/driver installed. If it is installed after any other
- "vector modifying program", it will function as expected.
- If not, it will not.
- (see EXAMPLE below).
-
-
- 3. SHIFT/PRINT SCREEN:
- CONTROL/PRINT SCREEN:
- MS DOS redirection (ie: DIR > PRN):
- These functions do NOT work with PD.COM if the utility
- is set to DISK, and they will hang the system.
- If PD.COM is set to PRINTER they do work normaly.
-
-
-
- OPERATION:
- Installation:
-
- The first time this program is run it will install itself.
- When installed, the resident portion occupies 1.6k of memory.
- NOTE- you MUST be in the same DIR:\PATH as PD.COM when it is first
- run.
-
- Every time PD.COM is run from the terminal after installation,
- it will close any open print files, and then it will ask you if
- you wish to go to the STATUS/MENU screen. It is from this screen
- that the various options of the utility may be set.
-
- Once installed, the utility will automaticaly open a disk file for
- output whenever a program attempts to print the first character
- of a report.
-
- This file will stay open, accepting more print data, until:
- 1. The program itself sends a CTL/Z (end of file) character;
- 2. PD.COM is run from the terminal; or
- 3. The NEXT program produces additional printer output.
- (Repetitive reports/printouts from the same program will all
- continue to go into the same disk file until that program
- is exited or it sends a CTL/Z to the printer.)
-
- When the file is closed in one of the above ways, the last memory
- buffer of printer data is automaticaly written to the file.
-
- NOTE- MS DOS will closes all files whenever an application program
- exits (stops). If you have just run a program that produced a printed
- report to disk, then there is still part of the printout in the
- utilities' printer buffer. The utility can sense this situation and
- will display a reminder to you on the screen, but it will not
- automaticaly write this last buffer.
-
- There are two ways to close this last file and write this last buffer:
- 1. Just run PD.COM from the terminal.
- (You need not go into the STATUS/MENU screen).
- 2. The next program that produces printer output will cause
- the last file to be closed and the last buffer written.
- Otherwise, if you look at this file (list it or edit it), the very
- last part of the report will not be visable.
-
-
- FILE NAMES:
- When PD.COM is installed each day, it will begin to open disk
- files as necessary using the name TMP01.RPT. As each file is closed
- and a new one opened, '1' is added to the number in the file name, and
- the next name becomes TMP02, TMP03, etc. up to TMP99.
-
- The utility will check the disk first and not use the name of any existing
- file, in other words, it will not destroy an existing file. When the
- number in the default file name gets to 99, the utility will automatacaly
- start over again with 01. If you have enough disk space and have used every
- possible number from 1 to 99 this program will go into an infinite loop.
- Since 99 report files would take up quite a few megabytes of disk space,
- and you, being conscientious, will be deleting these files after you are
- finished with them, this situation should never occur (hello Murphy).
-
-
-
-
-
-
- THE FOLLOWING ARE OPTIONS THAT MAY BE SELECTED FROM THE STATUS/MENU SCREEN.
-
-
- (OPTION) [A]ctive: (Print to DEV):
- This controls the destination of printouts, DISK or PRINTER.
- When the utility is installed, it automaticaly begins with output directed
- to the DISK. This can be changed to allow output to go to the PRINTER in
- the normal manner. From the STATUS/MENU screen, type 'A' to toggle from
- DISK to PRINTER and back.
-
-
- (OPTION) [M]essages:
- PD.COM will normaly print a message whenever it opens a new output file.
- This is handy as a reminder of the name and DEV/PATH that the new file
- is going into. But in some programs this will interferre with what is
- currently displayed. This option may be used to suppress these normal
- messages. Error messages will still be displayed.
-
-
- (OPTION) [N]ext file name to use:
- You may specify a particular device\path\filename for the next disk file
- name from the STATUS/MENU screen of PD.COM. After this next printout is
- completed, the file name will then revert to the next defualt file name
- assigned by the utility.
-
-
- (OPTION) [D]efault device\path:
- The device\path name of the utilities' next default file name can be
- specified from the STATUS/MENU.
- NOTE- This default device/path does NOT apply to a user specified
- file name (above), it only applies to the program's default names.
-
-
- (OPTION) [Z]ero history fields:
- This program keeps statistics on its activity just for general information.
- The current totals for day/month/total can be reset to zero when a new
- owner begins to use this program. The grand totals can not be reset.
- When the current fields are zeroed, the date installed field is updated.
-
-
- MISCELLANEOUS:
- FREE SPACE:
- The utility will show you the amount of free space available on its
- default device. Experience with printing reports to disk will help
- you determine if there is enough room left for your next report file.
-
- SAVINGS:
- From the above history fields, estimated savings can be computed.
- They are based on the assumptions that a page of paper costs 1 1/2 cents,
- and ribbons cost $10.00 per 2 million print characters.
- There is the additional saving of wear and tear on the printer itself
- (everything wears out), and also the intangible savings of time and
- trouble. But these, although real, can not be calculated.
-
-
-
-
- EXAMPLE of using this utility with a spooler.
-
- MS DOS's PRINT command is probably the most widely used spooler program
- available. This utility and PRINT can work together.
-
- To use both, remember to install PD.COM AFTER installing PRINT.
- Do this by first running PRINT without specifying a file name, PRINT
- will ask you for the device name of your printer. Answer as you normaly
- would. It will then announce itself as installed.
-
- Then, being sure you are in the same DEV/PATH as PD.COM, run PD.COM.
- PD.COM will then announce itself installed, and you are in business.
-
- To print 1 or more files with PRINT, first toggle PD.COM to PRINTER,
- and then print the files as you normaly would.
-
-
- NOTE- while they are printing, you can not toggle back to DISK until
- they are finished printing.
-
- When they are finished printing, you may then return to DISK printing.
-
-
- If you wish to install PD.COM in an AUTOEXEC.BAT file and you plan to
- use a spooler also, then do it this way:
-
- ... ; preceding commands
- ...
- ...
- PRINT ;install spooler first
- PD.COM ;install PD.COM last
- ... ; (be sure your in the same DEV/PATH as PD.COM)
- ...
- ... ; remainder of AUTOEXEC.BAT
-
-
-
-
- That's all there is to installing and using PD.COM.
- I hope that this utility will prove as usefull and convenient to you
- as it has to me.
-
- Remember, I make my living by writing software for sale. If you use this
- program, then I expect you to pay for it. I like the 'FREEWARE' concept.
- I have been burned by some high priced programs that just did not do what
- I expected (or what they claimed) and then could not return them. It is an
- advantage to be able to use a program first, and then BUY it.
- There are a few programs available on this basis, and there will be more,
- if YOU, the user, support this concept.
- If not, we all lose.
- I suggest a price of $15.00. But again, the worth of this program is the
- value it is to YOU. If you agree with the concept but not the price, tell
- me by sending whatever you do think its price should be.
-
- Thank you!
