- PRT
- by Peter Warren
-
- PRT is a simple printer buffer. The command would normally be
- included in the AUTOEXEC.BAT file, but can be used at any time.
- The first time it is used, the buffer is created and made ready for
- use. If PRT is executed at any later time, the buffer is emptied.
- To change the size of the buffer, (maximum=50k bytes), it is
- necessary to re-boot.
-
- EXAMPLES:
- PRT 50 will create a 50k Buffer (first use)
- PRT will create a 1k Buffer (first use)
- PRT will empty the buffer (subsequent use)
-
- Any data now sent to the parallel port (LPT1), will go
- very quickly into the buffer, and you can continue work while the
- printer does it job. A 50k buffer will hold 10-20 pages of text,
- but will soon fill up if the dot addressable graphics modes are
- used much!
