Hi. I'm unsure if this is the right topic, but since
GDI is mentioned i'll give it a go.
I need a very simple dll (COM/OCX) for printing reciepts at
a receipt printer.
The ideal functionality of the
function should be :
Print(string printername, string fontname, string PrinterOutput).
It's important that it's possible to use the native
fonts of the printer(Device Specific?), using TrueType
fonts will make the print slow.
I've looked around, but i've only found components that
by far exceed my simple needs.
Does anyone know a component that match my needs ?

Re: Printer Dll.
I have not seen such a DLL, but I have written programs for small printers. I used the standard fonts of the printers. I found the explanations I needed in the programming manuals that I could donwload for free from the web sites of the constructors. These printers have their own languages. I saw ZPL and EPL. You write lines of comands in a file, and then send the file to the printer via FTP or another way. Here is a commented example in EPL:
; Set label width in dots
; Select print speed 50mm/s (medium speed) 1is low speed, 4 is high speed.
; Enable direct thermal mode
; Enable top of form backup
; Disable Windows command mode
; Printing from top of image buffer
; Set form length 1218 with a gap of 25
; Clear image buffer
; Select font 8-bit, first resident font
; Define the location, font, and string of characters to be printed
; reverse(N=normal),"text"(in quotes)
