Printer stop printing

I use Samba POS V3. Now I install V4 in same POS Machine. But the problem is that first and second print ok, but when I print third time printer stop the printing. And I see that the printing is in queue. Printer is ok. Because in V3 such type of case is not raised. After restarting the printer it become ok. Can anybody help me to solve this problem please?

Can you elaborate?
Are these 3 exact copies of the same ticket template being manually printed with print bill button or 3 copies within the print job action or is it three separate prints - ie using kitchen and bar orders on single printer with separate print templates/jobs?
