Hi Stephen

I am using a cognitive solutions barcode blaster printer. All you do is send it a text file with parameters and then the printer prints the barcode.

Now I do the following:

cPrinter = getprinter()
set printer to cPrinter
set printer on
? "! 0 120 75 1"
? "PITCH 100"
? "VARIABLE FEED_TYPE GAP"
? "STRING 8X8 35 0 LESSON SCHEDULER"

I have determined that there is a blank line that gets printed first and I can't have this happening. The Blaster requires that the exclamation point be the first character.

The way I determined this was happening is that I set the printer to a file and then looked at the file.

Any ideas?

Thanks,
Paul


>>I have a utility that creates a text file and then copies this file to the parallel port by issuing the command "copy file 'file.txt' to 'lpt1'". This works fine because the barcode printer receives the file and prints the label properly. However, I get an error message that states the file cannot be created. I assume this error is because VFP cannot create a file called "lpt1"?

>You can add the same parameters for your system. I find it strange that a barcode printer will work on LPT1. Also is your printer cable designed to work with your printer? I have to purchase special cables for my printers {barcode.}
