Here is the 30 blank labels for your filling out.

Ummm... you might want to send a PCL code to throw
the printer into a more accommodating font for labels
if 25 characters long won't quite do it for you.

Each of the early "intelligent" printers are slightly 
different and may require futzing around with.  When you 
change all the PRINT statement to LPRINT (there are 5 of 
them) run the program for the first time on a blank sheet of 
paper (and not label stock) you may find your printer may 
not start to print even if you are in win98se and using an
intelligent printer.

At that point, press the formfeed key on the printer a wait 
a few seconds.  If it doesn't start to print, press it again 
and wait.  If the labels spacing comes out goofy, you didn't 
effectively replace all FIVE print statements with LPRINT.  

If push comes to shove, See TW.BAS for some PCL stuff. 
(printer control language) or hopefully, you have your own 
source of information on PCL.

GW-BASIC is getting some printing static from the later 
Windows operating systems after win98se.  So mainly to save 
yourself some headaches, just use this in DOS mode.  But, in 
any event, try it first, it may work anyhow.

Plus, to make matters worse, you may have to jitter-bug 
around with the T1-T2-T3 column spacing variables as well as 
throw in a couple of "print:print:print" lines in front to 
adjust vertical spacing. Hopefully, that may not be 
necessary.

Don't use label stock for checking out the spacing, just use 
normal 24# paper and hold it up to the light against a page 
of empty labels to check spacing.

Well, i tried the program and it works perfectly using 3x10
Avery 1810's (1" x 2 5/8") labels.  If you get any border- 
line letters onto the Labels, alter the DataLines by 
inserting a blank space in the data using typeover before 
the offending letter.  Then start your address in the next 
column.  But you shouldn't have to do that.  Don't forget to 
press the enter key after you change all 5 PRINT statements 
to LPRINT.

About the only use i can think of for 3 column labels is for 
sending out Christmas cards or maybe some other important 
announcement.  i used them for Christmas cards for a couple 
of years, but with a glue-on return label and a pre-printed 
crooked address label and a custom rubber stamp for a 
signature, i got the message and ordered another rubber 
stamp that said:

           "This impersonal Christmas card
            hastily sent to you has not been
            touched by human hands.  Pleas do
            not fold, spindle or mutilate."

Funny, i didn't get too many cards back after that  :-)
Anyhow, if you can use the 3up-labels, there it is.  All you 
gotta do is don't go over the opening and closing quotes 
with your crayolas when you enter the DATA (carefully)
