Printing Labels Fast on Elton printer

G

Guest

My program right now generates USPS style shipping label using
System.Drawing.Graphics. It works fine except that the printer prints really
slowly. I want to make my program take advantage of true type fonts. So I
assume it's possible to send Font Type and the text to the printer, and the
printer should digest and print faster. Still, barcode info needs to be sent
as an image.

When I print fifty copies of the same label it prints really fast (cache),
so I guess the printer itself is capable of printing fast.

Any idea's on how can I speed up printing labels using my c# program?

}

Absolutely not true. The Eltron printers have barcode-generation logic
built in. For example, sending this string to the printer:

"N" + chr(13) + "B10,10,0,3,3,7,200,B,""998152-001""" + chr(13) + "P1" +
chr(13)

would produce a Code 39 barcode starting at 10 dots down, 10 dots from left
margin, with a height of 200 dots.
Any idea's on how can I speed up printing labels using my c# program?
