Remarks on program function
The data for configuration of a virtual printer be updated, i.e. created, changed or deleted, with this program. Data which has already been stored can also be displayed.
The interface and link to an interface, processing unit should be defined and the device-specific operating mode of the printer set.
Note:
Virtual devices are only intended for test purposes if connection of devices is not possible for whatever reason. Java 1.4 or newer versions should be installed if virtual devices (printer, display, drawer, lock or EFT) are to be tested.
A device interface, type IP address should be configured and the device name, the local IP no. (localhost) and the port no. (5440) (localhost:5440) entered. In this example 5441 should be used as port no. for the virtual printer.
The following printer problems can be simulated in the program window of the virtual printer with buttons "clear", "paper end", "paper near end", "cover open" and "on" .
- On
Simulates the on/off switch on the printer. Error messages are sent by the terminal.
- cover open
Printer flap is open. An error message is sent.
- paper near end
Paper roll is nearly at the end. An error message is sent.
- paper end
Paper end. An error message is sent.
- clear
Clears the receipt window of the virtual printer.
Remarks on data fields
All options available for update of the basic data have been described below.
As with nearly all programs the following also applies here:
- The entry mask in the application program may differ for this program. Some data fields may be missing
- There may be some defaults or firmly defined selection options for some data fields. These cannot be updated in the current program.
- The entry mask contains fields where entry is optional and fields with enforced entry defined.
- If the data record is updated over several pages of entry masks, the dialog window is reached by clicking onto the appropriate button with <Mouse key 1>.
- The same procedure also applies to call-up of another update program from this program.
- In some cases, you may find so-called "Switches" which are activated or deactivated by the user with <Mouse key 1> depending on the setting. Activated switches have a dark top, deactivated switches are lighter.
Debug
Field with firmly defined selection options
Select one of the debug levels offered by clicking on this field and with a second click confirming the option selected.
The system offers the following:
- 0 = no protocol of data communication in file "errlog"
- 1 =
- 2 = all communication data in file "errlog"
Notes:
Only select a value higher than "0" for
the debug level if a protocol of the communication of the virtual printer is
required for error analysis.
Portnumber
Entry range permitted: numeric, 1 - 99999
Enter the port no. of the virtual printer.
Example:
"localhost:5440" is the entry for the interface, type IP address. In
this example port no. 5441 should be entered for the virtual printer.
Chars/line
Default 32
An entry here defines the number of characters per line to be printed on the printer.
BMP file
Path and name of BMP file for logo print
A logo can be printed on the receipt instead of the normal receipt heading. If this is stipulated the name of the BMP file must be entered in this field and, if applicable, the path in relationship to the current working directory (e.g. working directory = work.10, BMP file in directory xpm; entry = ../xpm/BMP-file name).
