[comp.sys.ibm.pc] TRS 80 LP5 double space?

wist@eniac.seas.upenn.edu (Bundy Wist) (10/10/89)

I just became the new ownwer of an ancient printer, the Radio Shack
TRS 80 Line Printer V. The problem is that when I print a file, it
gives two carriage returns for every one in the text.

According to the manual, there aren't any dip switches. I think that 
there must be some control characters that I need to send to the 
printer to print properly.

Does anybody else have this dinosaur? Any ideas on how to make it print
properly? It seems like a really fast printer and I would like to have it
printing without the extra spaces. Please email solutions.

Thanks in advance

There is a DIP switch on the main logic board that is documented in the 
Service Manual.  

Position 3 open causes a CR to generate a line feed also
Position 3 closed causes CR to cause a CR only

Position 4 open causes CR to be disregarded aftera LF or CR
Position 4 closed causes CR to NOT be disregarded.  

Sounds like switch 3 is what you need.  

The Service manual can be ordered from a local store or direct from 
Tandy Consumer parts (with a credit card).  Their number is 817-870-5600.

Try using the msdos command 'mode lfoff' which is supposed to 
remove lf characters if preceded by cr, or lf.
Hope this helps.

That command will only work if he is running TANDY MS-DOS. And
even then he'll need to run a couple of other programs to get it
to work right. (LF.COM and something else)
