<resolved> Software crash after several prints

Hello
I print the content of a form entirely by code such as:

VB Code:

Printer.CurrentX = 1000
Printer.CurrentY = 1200
Printer.Print txtName.text
 
Printer.EndDoc

by clicking on a print button which has this print code in click event.

Problem is that:
Although I can print the first few times, after several print of the exact same form my software can not send to printer any more (it simple freezes). I have to CTL+ALT+DEL to exit the software and reboot the computer and then again I can print! (without any change or correction to the code).
I am thinking that maybe there is a cach somewhere and I run out of memory. Is this correct? If yes how can I delete the cach after each print.
If this is not the problem then why do I have to reboot?
Thanks in advance.

Look at your systems event log to see a descriptive error message. It could be that your running out of
spooler stack space since you may be submitting print jobs faster then the system can handle.
