Printing

[drmover]

Hello,

Is there any way to send data to a printer using Basic4Android? Any library?

Can it be done from WebView or even from a regular screen?

Thank you,
Elad.

You might want to look at Google Cloud Printing.

I have ever printed by google cloud printing. you must have cloud printer or
computer attached printer and set cloud printer via crome browser before.
save file needed for print and use another application help to print.

As nfordbscndrd indicated, there are H-P and other printers that do tablet printing somewhat. I've got an app for basketball coaches, and I created the scoresheet on a canvas. Using "can1.Bitmap.WriteToStream(out1,100,"PNG")", the screen is saved. Then using "Gallery" or another photo viewer-program, you can print to one of the tablet printers. Hope this helps.

I have printed to bluetooth POS thermal printers

Timwil,

If you have any tips on how you accomplished that would be greatly appreciated. I have been trying to get Bluetooth communication to some portable thermal printers with no luck yet.

Thanks, Jim

Hi Jim

I am using a Citizen CMP10 and CMP20 - thermal POS Printer. First I pair it with my Android device then when I want to print I run the StartPrinter sub to connect then use pprint to send a line to the printer - like in the saleprint sub.

I am also exploring using the BTAdmin to automatically find the printer for me so I might not have to manually pair them together

Sub Process_Globals
   Dim cmp20 As Serial
   Dim printer As TextWriter
End Sub

Sub Printer_Connected (Success As Boolean)
   If Success Then
      ToastMessageShow("Connected successfully", False)
      printer.Initialize(cmp20.OutputStream)
   Else
      Msgbox(LastException.Message, "Error connecting.")
   End If
End Sub

Sub StartPrinter
   Dim PairedDevices As Map
   Dim l As List
   Dim res As Int

   Try
      PairedDevices = cmp20.GetPairedDevices
   Catch

   End Try

   If PairedDevices.Size = 1 Then
      cmp20.Connect(PairedDevices.Get(PairedDevices.GetKeyAt(0)))
   Else
      l.Initialize

      For i = 0 To PairedDevices.Size - 1
         l.Add(PairedDevices.GetKeyAt(i))
      Next

      res = InputList(l, "Choose device", -1)

      If res <> DialogResponse.CANCEL Then
         cmp20.Connect(PairedDevices.Get(l.Get(res)))
      End If
   End If
End Sub

Sub pprint(xString As String)
   printer.WriteLine(xString)
   printer.Flush
End Sub

Sub SalePrint_Click
   For xc=0 To slList1.Size - 1
      pprint(slList1.GetItem(xc))
   Next
End Sub

I am having a hard time also to print my documents and I am looking forward to see some help in here. I have tried also to use Bluetooth communication to some portable thermal printers but I still don't have luck.

What type of printer are you trying to print to?

What are you trying to print?

I have a POS program running on Android devices (phones and tablets) that store data in a SQLite database and print to a battery operated thermal printer.

Hi timwil

May i know how did you do it? the printing of your POS application to thermal printers using bluetooth. I am new to basic 4 android. I hope you can help me.

Thanks in advance

Hello,

Thank you for your reply.

Can it print from the WebView?

My main problem is to print HTML from WebView.

Thanks,
Elad.

 

[timwil]

Where are you trying to print to?

The printers I am using are receipt printers and I send information directly to them. Any special codes must be in the string of characters that I send.

If you are talking about HTML you would need to have some conversion to the printer language

 

[mangojack]

Presently printing HTML direct to a wifi printer using 3rd party app PrinterShare. Works well for personal use.

 

[timwil]

So what is it you are trying to do?

The PrintShare software would be doing the formatting - or converting the html into the format the printer can understand.

There is a program called printbot that you can print from your phone to an IP printer. I think this is what he is trying to do. Be able to print something out. It's a little program that runs and gives you to option to print things instead of showing them onscreen.
