COMMENT^ ** SETPRN.COM ** Last Rev. 3/11/91 ** Vincent T. Bly **
| |
| PURPOSE: Provide a easy method of setting printer parameters |
| from the DOS command level or from a batch file. |
| |
| FUNCTION: Send a user specified text string to the printer. |
| The string may contain control characters consisting |
| of decimal numbers enclosed in brackets ("[" and "]"). |
| The normal ending carriage return/line feed may be |
| suppressed by a trailing semicolon (";") or comma (",") |
| in the same manner as the BASIC LPRINT command. |
| |
| TO USE: From DOS, type SETPRN followed by a space and the text |
| string, then press . For examples, see the file |
| |
| TO MAKE: Assemble with MASM or TASM and link with LINK or TLINK. |
| Convert the resulting .EXE file to .BIN with EXE2BIN. |
| Convert the .BIN file to .COM with RENAME. |
| |
| NOTE: For the sake of simplicity, SETPRN does not make |
| extensive checks on the current state of the system. |
| This could conceivably cause problems in a multi-user |
| environment. |

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read:
