I've had problems with OPOS (EPSON version) working on some of my W2K machines. I had an older machine running W2K that wouldn't run a specific version of OPOS (don't remember why anymore). But I remember that it did work once I changed machines. Try another W2K computer and see if that helps or better yet, try to get another OPOS version. Maybe the older OPOS version will work, whereas the newer one won't. You'll have to experiment.

>>After I Open and Claim the printer, I set the DeviceEnabled property to TRUE and AsyncMode to FALSE. In the Destroy method of my form, all I do is:

>>IF THIS.oleOpos.Claimed  && THIS == THISFORM
>>   THIS.oleOpos.Close()
>>ENDIF

>>I do not set the DeviceEnabled property to false. That is all I do.

>>>I had tried your method, but it still give me problem like showing hour glass and halt my system. I am using the OPOS printer driver. Do your know what is wrong ?
