Printer in Ubuntu
Issue #176
new
Hello. Simple application code. It prints using Printer module.
Printer.BeginDoc;
Printer.Canvas.TextOut(0, 30, 'ЧЕК');
Printer.Canvas.TextOut(0, 60, 'Дата: 20.02.2019 Время: 10:25');
Printer.EndDoc;
On Windows printing is good, but on Ubuntu this code does not print appropriate.

What if you print in other apps ?

I have printed text file from LibreOffice Writer. It printed very well, like in Windows.
I guess problem in module Printer when CrossVCL converts it?

I am trying to create PDF, and then print PDF file. I have used library Synopse PDF Engine https://synopse.info/fossil/wiki?name=PDF+Engine On Windows this code works well.
procedure TfmMain.btnPDFClick(Sender: TObject); var lPdf : TPdfDocument; lPage : TPdfPage; begin lPdf := TPdfDocument.Create; try lPdf.Info.Author := 'Tester'; lPdf.Info.CreationDate := Now; lPdf.Info.Creator := 'Tester'; lPdf.DefaultPaperSize := psA4; lPage := lPDF.AddPage; lPDF.Canvas.SetFont('Helvetica',10.0,[]); lPDF.Canvas.SetLeading(lPDF.Canvas.Page.FontSize); lPDF.Canvas.SetLineWidth(0.1); lPdf.Canvas.BeginText; lPdf.Canvas.TextOut( 30, 820, 'ЧЕК'); lPdf.Canvas.TextOut( 30, 800, 'Дата: 20.02.2019 Время: 10:25'); lPdf.Canvas.EndText; lPdf.SaveToFile(ExtractFilePath(Application.ExeName)+'test.pdf'); finally lPdf.Free; end; end;PDF-file created. But library Synopse does not deploy through CrossVCL :(

Synopse PDF Engine is only for Windows. You need ask for authors to support CrossVcl. Or we will try to add support of it later.

About printing - just tested on regular HP printer - looks fine. Can you try to select different font and size ?

Starting from 1.55 you can create PDF using metafile. See Metafile example.

Sorry, image of check is wrong. The right check is attached. Printer is receipt printer Rongta RP58 http://www.rongtatech.com/products-look-8.html I have got a driver for Ubuntu from manufacturer Xiamen. The driver is installed correctly on Ubuntu.
