Information Systems Q&A

About Drivers and application development

A1:For the status of Windows Driver support for product and OS, refer tothe download site of each driver.

A2: Some products are provided with WindowsDriver having status monitor.
For the status of product support, refer to the downloadsite of each driver.

A3: In the printing with Windows Driver, paperis fed automatically to the cut position after printing.
As this paper feed inserts a blank corresponding to the space betweencut position and print start position at the top position of printing,this blank part at the top of printing cannot be reduced in theprinting with Windows Driver.

A4: Yes. It is possible to use the driver bychanging the setting.
Windows2003 server accepts User mode driver only as default and refusesthe Kernel mode driver which can be used on NT4.0/2000/XP. If youchange this setting, you can use NT4.0/2000/XP driver on Windows2003Server. The method to change the setting is HERE.

A5: Please refer to the explanation aboutterminal service and printing from Microsoft
http://download.microsoft.com/download/4/6/b/46bae314-ea7b-4c39-bcb6-defbc907ee54/TSPrint.doc
and follow the explanation.
If it still does not solve the problem and if you want to cut the paperat the end of printing, you can add cut function in the following steps.
Find GPD file such as CBM1000II.GPD in 1.xx driver files.
Open the GPD file by the editor, NotePad for example, and you can findfollowings around the 300th line.
*Command: CmdEndJob
{
*Order: JOB_FINISH.0
*Cmd: '<000000>'
}
Change the above '<000000>' to '<1D>V<01><00>'.
('<1D>V<01><00>' is partial cut command.)
Then you can have partial cut at the end of printing.
It is also recommended to change version in *GPDFileVersion: '1.xx' ofthe 3rd line.

A6: MS-Access does not allow longer paper sizethan 57.78cm (22.75inch). Therefore the default paper size of ourprinter (3276mm) cannot be used with MS-Access. Please choose shorterpaper size as A4 length.

A7: Those characters should be printed in graphics. CD-S500 is dot matrix printer and its resolution is not high.Therefore the characters printed in graphics are not clear. If you want to print good looking characters, please use printer fonton the application software or set the graphic mode of driver to Standard or High quality mode.Refer to the driver guide which comes with Windows driver. If you use Standard mode or High quality mode, printing is slower than draft mode (default).

A8: It may be the wrong baud rate setting for the virtual COM port or the driver is not correctly installed. If the correct baud rate (115200bps) does not solve the problem, it is recommended to remove the driver and re-install it once again.To uninstall the virtual COM driver, execute the uninstaller (FTDIUNIN.exe) which is included in the folder of V-COM driver.

A9:: Yes, there is no difference between Windows Embedded and Windows.Therefore, if the necessary components or files are included in Windows Embedded the Windows driver should work without any problems. However, many Windows Embedded systems do not have all the components or files loaded on the system. This is the most common cause of the driver not working. In this case, please consult with the machine manufacturer.
The necessary components for Windows driver are as follows:
?System Restore Core
?Error Reporting
?Communication Port
?Local Printing Support

A10: It seems that if the re-directed driver from the client is used from the application, it causes the problem.
If you make the driver on the client to be shared and use the shared driver on the server, the problem should be solved.
This problem will not happen with next version driver.

A11: Using the special printer font function of the driver to open the cash drawer on a ?.Net? application will not work because the printer font is not supported by ?.Net Framework?. Instead, use the printer driver function to automatically open the cash drawer. The details of this function are detailed in the driver manual.

A12: The first driver listed in the download page for POS printer driver supports Vista currently.
English version
Chinese version
The driver for PD22/24 supports Vista as well.
Drivers for barcode printers support Vista also.

A13: Please adjust the paper size in the driver properties.
How to Create Custom Forms in Windows
(These sites are for Windows NT or 2000 but they are also applicable for XP and Vista.)

A14: Select Landscape orientation is available.
If you are developing an application for Landscape printing, please program like following example.
Example for VB6
??Printer.Orientation = vbPRORLandscape ? 'Horizontal direction
??Printer.Orientation = vbPRORPortrait ??'Vertical direction(Normal)

Citizen Idp 3550 Printer Driver

A15: We can supply CUPS drivers based on your request.
Please note: although our web site gives instructions for downloading CUPS driver basic knowledge for Linux and CUPS is required.

A16: We supply a SDK (Software Development Kit). It includes sample programs for five development languages (AppForge, Compact.NetFrame C#, Compact.NetFrame VB, EmbeddedVB, EmbeddedVC) to work with CE drivers.
It is worth noting, since the mobile device handles IrDA and Bluetooth as a COM port, many customers made have written their own applications to communicate to the printer directly using a COM port. This illuminated the need for a CE driver.

A17: The SDK includes card reader functionality in Qx. For other application development issues, please refer to Qx.

About communication

A1: The status of supporting USB interfacedepends on the product.
Refer to the product informationsite for the interface specifications of the product you arestudying about adoption.
If the interface specifications include a “USB” description, theproduct complies with the USB interface.

A2: Refer to the host-to-printer interfacespecification of the user’s manual for the connection of serialinterface cable.
A typical example of connection is shown below.

Though the product has been verified that it can operate with across cable (reverse cable) generally sold in the market, do not use acable with unusual connection.

A3: For serial interface, the cable length isspecified as 15 m maximum in the RS-232C standard.
For parallel interface, the cable length is specified as 10 m in theIEEE1284 standard. However, the longer the interface cable, the moresensitive to external noise, resulting in the cause of communicationfailure.
It is recommended that the interface cable be as short as possible.
If a longer interface cable must be used by any means, make a study ofnoise prevention in accordance with the environment of use.

A4: There is no product that can comply with RS-422/485 among the products handled by our company.

A5: There is no product that can comply with current loop among the products handled by our company.

A6: The support status varies with the product. Refer to the productinformation site for the interface of the product you are studying about the adoption.
As the product having a description of parallel interface specification (IEEE1284 compliant) supports bidirectional communication, acquiringthe status is possible.

A7: Refer to the following description on the connection of interface.
For other wiring (such as power supply), refer to the user’s manual of the product you purchased.

A8: The USB interface has a default serial number of '00000000' for many printer models (CT-S2000/CT-S2010/CT-S4000/CT-S310). Because of this, the PC cannot distinguish a difference between the two USB printers causing the PC to hang. To fix this, USB serial numbers need to be individually set for each printer if you want to connect more than 2 CT-S printers to a PC. With unique USB serial numbers, Windows driver installation is required for each printer.
How to change the USB serial number
Please use the Printer Customization software. The software can be downloaded from our site.
Japanese version (No.6 is the software)
English version (No.6 is the software)
The function to change USB serial number is located from Menu
File=>USB Serial No Regist

A9: Please refer to the file showing the recommended wiring.

About other functions and specifications

A1: As a method of setting print density,printer function setting command is available. For details of thecommand, refer to Command Reference.
Command Reference can be downloaded from the downloadsite of command reference.
In addition, a tool for customizing printer function like print density(Printer Customization) is provided.
This customization tool can be downloaded from the downloadsite of utility software.
* No. 6 in the download site corresponds to the relevant tool.

A2: Methods with Kanji control command and printercustomize command are provided. For details of command, refer toCommand Reference.
Command Reference can be downloaded from the downloadsite of command reference.
A tool for customizing the printer function such as Shift-JIS/JISswitching (Printer Customization) is also provided.
This customization tool can be downloaded from the downloadsite of utility software.
* No. 6 in the download site corresponds to the relevant tool.

A3: Considerable amount of current flows in thepower cord during printing operation in accordance with thespecification of the product.
As the method of connection for power cord may cause voltage drop inthe power cord, it is thought that printer operation may fail due tounstable voltage applied to the printer.
To keep the voltage applied to the printer stable, the following threepoints must be considered on the connection of power cord.
(1) Power cord connection
The longer the power cord connection, the more the effect of thevoltage drop in the power cord, resulting in negligible effect.
Be sure not to let power cord connection be excessively long.
(2) Separated wiring
Avoid the wiring with +5V and GND for driving and control linesgathered to +5V and GND respectively up to the power supply.
Wire +5V and GND for driving and control lines separated from eachother up to the power supply.
(3) Power cord wiring material
In order to reduce the effect of voltage drop in the power cord, usethe wiring material with thick core diameter and smaller conductorresistance (AWG20 or AWG18).

A4: Angle of elevation 10°/angle of depression 5°is a rough target for the standard of vertical surface.

A5:There are two different ways depending onBluetooth module that you are using.
(Old type Bluetooth module) If its serial number issmaller than 0640001 or self print shows firmware version 1.xx, enterthe last 4 digits of 'Address' in numbers or lower case characters.
Example Address: 00 0A D2 10 1F FD => PIN code '1ffd'
(New type Bluetooth module) If the serial number islarger than 0640001 or self print shows firmware version 2.xx, enterthe last 4 digits of 'Address' in numbers or upper case characters.
Example Address: 00 01 90 E1 A2 CF => PIN code 'A2CF'With new type Bluetooth module, you may be required to enter PIN codeevery time when you connect from PDA to the printer.
This is because CMP-10BT does not save the information of connectedBluetooth module.
To change the setting to save the connected Bluetooth moduleinformation (Pairing Information), please refer HERE.

A6: Because the print speed of CT-S2000 is fast, itis expected to use high sensitivity paper for CT-S2000.If you usestandard paper, we recommend to set CT-S2000 to high quality printingmode. To set CT-S2000 to the high quality printing mode, memory switchMSW5-6 should be ON. Maximum printing speed in high quality printingmode is same as standard mode.

Precautions in printer switching

•The distance from print start position to manual cutterposition is different.
If the print data created for CBM-270 is directly printed with CT-S280,the margin at the top of printing is narrowed and the margin at thebottom is widened.
<Reference> Distance from print start position to manual cutterposition: Approx. 13.5 mm for CBM-270 and approx. 8.4 mm for CT-S280.
•Communication speed of 1200 bps is not supported.
Communication speed of 1200 bps supported by CBM-270 is not supportedwith CT-S280.
