问题 Hey printing junkies need some pointers to send me in the right direction for this development.

问题 Hello lovely community! I am using a HP 2x20 Integrated Display with HP RP 7800 Retail System and decided to play with it and write some small programs for it to learn coding. The sample tool provided with the SDK works perfectly. First I wrote a simple program using Microsoft.IO.Ports and simple functions like this: SerialPort COM3 = new SerialPort("COM3", 9600, Parity.None, 8); COM3.Open(); COM3.Write(Clear); // string Clear = "\x1B\x40" - hex value of a control character for the display

问题 I am writing a point of sale application for a client who has some very specific needs. The client is a retail store, so when they process credit cards, they have a physical card present and can swipe it. The way it is now, at the end of check out, it presents the cashier with a total, and the cashier keys the total into a credit card terminal (by hand--it is not connected to the computer), swipes the card at the terminal and then when the payment is processed, the cashier presses the "Paid

Currently I'm working in a team creating a custom POS solution. We came to a point were we'd like to integrate with a IC/Credit Card terminal (like VeriFone which we have, i.e. Vx510).

The reason the printer is so slow is that it's using the graphical font functions of Windows.

I've been trying to programatically feed the paper on a pos printer (Epson TM-U220D). The problem I have is that the last line of the document don't get printed, instead, it is printed as the first line of the next document printed. I tried POS for .NET sending the "ESC|flF" command, also tried to send the raw esc/pos command using the serial port, but it doesn't work. Any ideas?
