Zebra Z4MPlus won't print barcode in Windows 7 Professional.

Hi there,

Please go to the inhouse program & click printer properties and
change the printer setup to direct thermal and that's it.

Ok,

This machine has a parallel port. Try to print via parallel cable. If it works, consider staying with it. Serial ports are a pain to manage.
If you absolutely have to do it via rs232 though....
Question 1. Has it ever printed?
If yes, Go into Windows Printers and Faxes control and select the Zebra or whatever printer that you are using. Right click on it and you should get a menu that at the bottom say "Properties", select that, then you should get a new window with tabs at the top. You want the tab for "Ports". Select it and you will see all of the different output ports that you can direct your printing. RS232 is a COM port. So start at COM1, check it and try to print. If that doesn't work, go to COM2, etc.

Last resort, If you can't get control via the printer driver program, you will have to try redirecting the print manually (now you will understand why I said to stay with parallel output).
What you have to do is redirect your printing via the dos "mode" command.
Under "Start Menu" goto "Run" and put in "CMD" and click "OK".

This opens a black square window with a cursor blinking. Type in this:
mode com1:9600,n,8,1 (enter)

mode lpt2=com1 (enter)

Tell your program to use LPT2 if you can and see if it works.
By now a parallel cable instead of RS232 should be looking really good.
Good luck!

Try using the Seagull Scientific Zebra driver. It is usually a much better code driver that the original ZB one.
