Double space printing

Posted on 2001-06-06

whenever i print from the DOS editor
the printer prints it in double space mode.

i.e.,2 lines of text take up 3 lines with an empty line
between the first and second.

I have Windows 95 on my machines.
I have no printers installed under PRINTERS.
I tried intsalling the appropriate printer driver but of no use.

This problem exists only on one particular computer(I have two computers).
All printers(I have three printers, all EPSON) behave likewise if they are
connected to this particular computer.

It seems the problem lies in the OS.

Please help.

Check to see if you can find a printer manual somewhere

There is usually a dip switch setting for lf / lf+cr.

If the switch is set wrong you can get double spaced printing.

If all the lines print on top of each other you also need to change the setting.

This is the best answer I can think of for the moment without asking lots of other questions

I think kneea has it, dos text files put a carriage return <cr> and a linefeed <lf> at the end of each line, either of these can be interpreted as a newline command by a printer, in theory, <cr> should just home the cursor, and <lf> should just advance the line, but both commands do both on a lot of systems. Dos text editors tend to have problems with text files from other systems because of this, when they don't have both.

I also agree with kneea.  I would add that to get to the heart of the matter, you need to tell us what model printer you have (an Epson what?).  As far as DOS, check the Options > Settings menu to make sure that you have 8 tab stops (default).  If you have 2 connected printers, try printing to the other LPT port, which you can change here as well.  If you haven't updated your motherboard's BIOS lately, go for it.  There may be an update that specifically addresses DOS printing.

As a last resort, try changing your LPT/Parallel setting in your PC's BIOS.  Many new printers use ECP or EPP, but you may want to try something different, like AT or PS/2.  You may also want to check that the I/O address is 378h.

DO you run "scandisk" with "automatically fix errors" in Windows mode regularly?

Hmmm I wonder if the stuff you are printing has any wierd characters in it that the printer interprets as "escape" codes. When it works fine on other machines with the same printer are you printing the exact same thing??

Road warrior could be correct and it is possib;e

To be sure, when the printer starts printing in double spacing, turn the printer off, and then back on, and try again. If the document starts double printing in the same place for a second time you have control codes in your document.  Either use an ascii filter (to remove all ascii below 32 and apart from 10 and 13) or print the file from notepad in windows.  (it will be slow though)  Word perfect, wordstar or something like that for DOS might also get around the problem and won't take ages to print.

Is this printer connected to a serial port by any chance?

IF A PRINTER PORT (THE SOCKET WITH HOLES IN IT) IS WHAT YOU YOU MEAN THEN IT IS, WARRIOR

Oh the one with the holes in is the regular printer port, just wondered, because serial printers can do funny things like this when the protocols are set wrong.

hmmm, I'll see if I have another idea.

RE:

Try this procedure....

1) enter some text in 'edit' like you did above

2) print it

It should be double space like you mention above

3) turn off the printer

4) print it again

Is is still in double spacing?

5) exit the 'edit' program

6) type 'mode' at the dos prompt and let us know what it says.

This is whay my computer says...

C:\WINDOWS>mode

Status for device LPT1:
-----------------------
LPT1: not rerouted
Retry=NONE

Code page operation not supported on this device

Status for device LPT2:
-----------------------
LPT2: not rerouted

Status for device LPT3:
-----------------------
LPT3: not rerouted

Status for device CON:
----------------------
Columns=80
Lines=50

Active code page for device CON is 850
Prepared code pages:
  code page 850

We should then know what causes the problem.
