Printing and Selecting Fonts

shercua

I have a question regarding receipt printer. I'm figuring out how to select different fonts like Times New Roman, Arial, Tahoma, Courier, etc. Do you know the ESC (escape) commands for selecting fonts? And for example if the ESC command is ESC M, how do I write the font name that I want to use? Am I just going to add the font name after the ESC command? Other alternative is do you know how to select fonts using C#.Net? I'm going to write the code in the class file (and not in the form file), and I'm using Windows 2000, serial connection, and API commands using Winspool.drv (eg. WritePrinter, OpenPrinter, etc.) ANd after selecting the desired font, what will happen if I initialize the printer again? Will it retain the font that I selected? Thanks for your help! I really appreciate a quick reply. Thanks!

Learn about Windows. It has many installable fonts and they are sending to printer as graphics by GDI. It was designed to avoid troubles with different printers. See System.Drawing namespace in .NET. I understood that You didn't want to do it and You want to use printer fonts. Every printer has own fonts and own commands. There are some standards like ESC/P, ESC/P2 or HP ... There's no C# commands to choose them, only ESC. If exists printer command to set default font - You can use it.

Thanks for your reply. But I went to the ESCP2 link and I just found 9 kinds of font. Is there any way you can choose more than 9 fonts? Also, is there a command in C# where you can set the default printer font? So even if I initialize the printer, the default font will remain the same. Thanks

Every printer has another esc commands ... near always font codes not font names ... For ESCP2 see here For HP see here Search Google with "ESC printer commands" After initialize You must select all printer options again - there's no good solution. I set codes before every new page.
