Dot Matrix Printers

We have tried to summarise, some of the most frequent FAQ's for Dot Matrix printers on these pages and will endeavour to keep the pages updated on a regular basis. If you would like to submit a query (which may well feature on these pages) support@avdcs.com.

We will endeavour to post more info in the near future.

Q. My Printer was working fine under Windows v3.x but I have recently upgraded my machine to Windows95 or NT.

A Go back to Windows v3.x but more seriously .......

Q. My Printer was working fine under Windows v3.x but I have recently upgraded my machine to Windows95 or NT. I have installed the Print driver supplied with the printer but it stops printing halfway through the test page.

A. It has recently been observed that the use of Bi-Directional (ECP/EPP) Parallel ports can cause problems with printers, particularly under Windows 95. This would appear to be related to the Internal cabling of the Computer and it is difficult to be more specific, some computers work, others seeminhly identical dont. AVD therefore recommends that at least for testing purposes the supposed ECP/EPP capability of your computer is turned off. This will probably involve you going into the BIOS set up, so dig out that old manual.

If you are using Windows 95 (WHY?) then the Parallel Port mode can be seen under the Hardware Manager settings.

Q. Will Windows v3.x Print Drivers work under Windows95

A. Ask Microsoft - According to the marketing blurb this is supposed to be a seamless upgrade but in reality....... The Print Driver supplied with your printer was probably for Windows v3.x or from the Microsoft Windows v3.x disks. Try using the SEIKO Precision Print Driver from the Windows95 CD-ROM (or disks). Should this still cause problems you should try to use one of your Printers Emulations. Most SEIKO Precision Printers support an Epson emulation and in many cases an IBM emulation as well. You could also try our Print Driver page.

Printers supported when using Windows v3.x

All SEIKOSHA Printers will work correctly under Windows v3.x using Printer Emulations. Typically these are for Epson and IBM models, to see a list of Printer Emulations go to the emulation page. Microsoft supplied SEIKOSHA specific print drivers with Windows v3.11. Unfortunately these are hidden from view and are on Disk7. To access them Click on "Install Unlisted or Updated Printer" and when prompted insert Disk 7 in Drive A: or Drive B: you will then see the following SEIKOSHA printers listed:

Can also be used on

Q. When using Fanfold paper the printer appears to print the first page, then throws 2 forms before resuming Printing

A. Who hasn't read the manual then ? If you look at your printer you will see a small lever protuding (normally on the right hand side) which shows a picture of Fanfold paper (normally at the front) and Single Sheet (normally at the back). This lever sets the printer into fanfold or Single Sheet mode. From the above our guess is that this lever is set to Single sheet and the printer is trying to find the end of the paper. Pull the lever to the front (Fanfold) position and the problem should go away.

Q. My Printer (SP or SL-9X range) suddenly stops printing in the middle of a form and the P.OUT signal flashes

The SP range and the SL-9X range (incl SL-150) use a P.OUT sensor which measures the reflection of light to detect the end of paper. If you are using Pre-Printed forms it is likely that a Black area exceeding 0.5inches has been detected by the sensor. There are two ways to get round this problem.

a) Redesign your Pre-Printed forms to reposition the Black area away from the sensor.

b) If you have an SP printer you can disable the P.OUT sensor by sending down an ESC 8 command (only available in Epson mode). WARNING By disabling the P.OUT detection in this manner you run the risk of increased paper jams and damage to the Printhead if you allow printing direct on to the Platen.

Cut Sheet Feeder Set Up using SL-90 Plus Windows Driver

Universal Printer Driver V.3.1.4

SL-90 Plus Driver V 1.0 1990-1992

In set up it is necessary to set PAPER SIZE as USER DEFINED

set size to A4 Width 2100 Length 2970

TOP MARGIN

The printer is incapable of printing on the TOP 0.38" of the document so to set a TOP Margin of 1" insert MARGIN SETTING of 0.62 this is 1 - 0.38

For a margin setting of 0.75" insert MARGIN SETTING of 0.37 this is 0.75 - 0.38

Setting the TOP MARGIN SETTING IN THE SOFTWARE TO ZERO will give a Top Margin of 0.38.

BOTTOM MARGIN SETTING

The printer cannot print on the bottom 0.3" of a document so it is necessary to set bottom margin at 0.3 GREATER than the required Margin.

E.G. 1" will be set at 1.3. 2" set at 2.3

ON testing the bottom margin setting a minimum of 0.7" was found to function successfully.

LEFT and Right MARGINS appear to have no restrictions within reason.

To get the first print position on the Left hand side of the document Set the Left hand paper guide on the SHEETFEEDER on Ruler mark 0.8

General Questions asked

On our help desk we get a multitude of questions and problems thrown at us. In general these are down to users not reading the manual and/or incorrect settings on their Printer or Computer. We have tried on our Emulation page to give advice on the best Print Driver to use, when a SEIKSOHA driver is unavailable. Hot Spots on the Emulation page will give some basic advice on Dip Switch settings and Self Test printing.

Before calling or contacting us, please try the following

Hardware Set Up

FOR DOS, OS/2 or Windows users

  • 1. Turn Printer on, DO NOT Connect to your Computer
  • 2. Print the Self Test. The test print tests everything on the printer except the Computer Interface. If the Self Test works, this would normally mean the printer is fine and you should look at Computer, cabling, and or software problems.
  • 3. Assuming the Self Test works, then connect the printer to your Computer and if necessary turn the Computer on.
  • 4. Go to a DOS prompt. This should show a black page with a prompt on the side showing C:\> or something similar.
  • 5. Create a small text file by typing the following at the DOS prompt, DIR>TESTING.TXT
  • 6. After pressing Enter the file TESTING.TXT will be created. (This file can be edited using a standard DOS editor, EDLIN, E, EDIT etc). Assuming your Printer is attached to the only Parallel Interface on your Computer, this file can also be printed by using the following Syntax. TYPE TESTING.TXT>LPT1
  • 7. If your printer is connected to a COM (Serial port) then substitute COMx (where x is the COM port Number) for LPT1.
  • 8. If the above worked and legible text and numbers were printed, you have now shown that the Computer Interface, Computer to Printer cable, Printer Interface and Printer are working fine and can talk to each other. The only thing left is the software setup.

Software Set Up

  • 1. In order to verify the software set up you will need to know some information about how you have changed the Dip Switches or set up settings. On more recent printers this information can be printed out. For instructions on Dip Switch setting print-outs check the hot spots on the Emulation page.
  • 2. Make sure that you know whether your printer is set to Epson , IBM or any other type of printer. Ensure the Computer software is set for the same type of printer. For full model Emulations check the Emulation page (or even better the manual). Try printing a very simple page (5 or 6 letters will suffice). All you are testing is that the set up can talk to each other.

Q. Why are the Printer fonts not available in OS/2 Warp

A. The OS/2 Print Drivers for Epson printers send all jobs down as Graphical Bit-Maps. (If any-one knows differently please let me know). This slows the machine down considerably. The best way we have found to use at least some of the printer fonts is to set the Printer to use its IBM emulation (if it has one) and then use the OS/2 IBM Print Driver. This enables at least the Courier Print Font, and will speed up text printing considerably. Unfortunately not all of our printers have an IBM emulation so printing will remain bit-mapped. The WINOS2 sessions can utilise normal Windows v3.x drivers and these include those on our Drivers page or those supplied with either OS/2 or Windows.
