Problems with Pretec BT card, communication when printing.
Posts: n/a
8800, operating system 2003 and Zebra printer QL 420.
What is more there were no problems when I was using BT card from
Anycom or Socket. It seems like communication between Pretec and Zebra
printer was crowded.
My application is written in visual basic, I use control like comm.
I tried to delay close communication operation but with no result,
after few lines printer stops printing and BT light blink like mad.
I would be grateful for any suggestions.
