Report SharpShooter and Receipt Printers....

Edhy Rijo — Tue, 20 Oct 2009 08:56:59 GMT

Hi guys,

I have the need to generate 40 columns receipts using standard Receipt Printers like the Star SP200 or the Epson series. Have you guys used Report SharpShooter (RSS) with these kind of printer? if so how would you control the receipt's length so when the receipt finish printing it will only eject a couple of line to cut the paper?

In my case, I use the "Generic Text" print driver since I don't have any special needs for using a custom driver yet.

Thanks!

Hola Juan Carlos,

I am sorry I skip this post. Thanks a lot for this information, I will review it and let you know if I can use it.

Hi Edhy

You can take a look to this resources:

http://social.msdn.microsoft.com/Forums/en-US/posfordotnet/

http://www.microsoft.com/windowsembedded/en-us/products/readyproducts/posready/default.mspx

This a POS implementation for NET. Could be usefull, I found an aplications (AEVI POS) that use this libraries.

That's great Paul, thanks again, I will implement this now.

Edhy here is a stripped down version of what I am using hope it helps.

'--Local variables

Dim hPrinter As New System.IntPtr() 'Printer Handle

Dim DocInfo As New Base.Printing.Strucs.DOC_INFO

Dim lnWritten As Integer = 0

Dim LoString As New StringBuilder

'--Open Printer

If ActionLabor.Payroll.Base.Printing.PrintAPI.OpenPrinter("receipt", hPrinter, 0) = False Then

Return False

End If

'hPrinter contains the handle for the printer opened

'If hPrinter is 0 then an error has occured

If hPrinter = 0 Then

Return False

End If

Try

DocInfo.DocumentName = "Rcpt# " & Me.RctNbr

DocInfo.DataType = "RAW"

PrintAPI.StartDocPrinter(hPrinter, 1, DocInfo)

PrintAPI.StartPagePrinter(hPrinter)

'set output to printer

LoString.AppendLine(String.Format("----{0}----", "Header"))

LoString.AppendLine("Line2")

If Not PrintAPI.WritePrinter(hPrinter, LoString.ToString, LoString.Length, lnWritten) Then

Return False

End If

Catch e As Exception

'ToDo:--Add Here

Return False

Finally

'Close

PrintAPI.EndPagePrinter(hPrinter)

PrintAPI.EndDocPrinter(hPrinter)

PrintAPI.ClosePrinter(hPrinter)

End Try

Return True

Edhy here is a class wrapping API printer calls that I am using. I see if i can pull an example using it from my code in a few.

Thanks Paul,

I have to work on this today, so I will explore the API method.

RE: Report SharpShooter and Receipt Printers....

Paul Chase — Fri, 16 Oct 2009 09:21:21 GMT

Edhy I use DevExpress as my reporting tool so can't comment on SharpShooter. However I did run into issues several trying to use a report writer for this type of thing. I ended up talking directly to the printer via API calls and at least in my case it was easier and gives me the level of control I needed.
