You have posted the same question in ClassicVb.

Are you doing this through a VB program or through VBA?

Assitance you get from this section will be VBA specific which might not work with VB; conversely any assistance you get in ClassicVb with be VB specific and might not work in VBA.

I'm doing this with both VB and VBA, in fact I'm making an MS.Access program which require to print out text on a printed form. Thank you for your direction and inttention

You need a manual to the printer to get the escape codes. Are you writing a driver or was that someone else? I saw a few links to this forum as well.

I've got the manual, but i didn't know what must I do at first. Some escape code work properly but I can't print out the text. My VB code is as follow:
Visual Basic 6.0
PrnPort.CommPort = 1
PrnPort.Settings = "9600,n,8,1"
PrnPort.ParityReplace = "?"
PrnPort.Handshaking = comRTSXOnXOff
PrnPort.PortOpen = True
PrnPort.RThreshold = 1
PrnPort.SThreshold = 1
PrnPort.DTREnable = True
PrnPort.RTSEnable = True
PrnPort.Output=”Hello” & Chr$(13) & chr$(10) ‘Print out the text - perform no action
PrnPort.Output=Chr$(&H1B) & Chr$(&H4F)) ‘Esc O Eject paper - working properly
