Printer format problems after moving 4.53DOS applications to LegEasy4DOS

Download: document004.pdf

I am unable to recreate printer output from LegEasy4DOS in that the overall 4.53 print layout is moved 1/2" right increasing the LH margin and an additional line of unknown characters precede the top data line and follow the last printer line. Also some 4.53 printer control characters embedded in the output print definition, such as change to 5cpi, are ignored.

Attached documents 001 and 003 are printed from 4.53 apps running under WinXP. Documents 002 and 004 are LegEasy4DOS output for the same apps running under Windows7. The printer being used is Brother HL-L5000D which Is using parallel port LPT1 from WinXP and a USB port from Windows7. The same printer layout codes are being used on both systems.

Because of the use of printer control characters in the printer output definition the printer output file has been set to RAW. Consequently  I would expect the output received by the printer to be identical unless there are hidden differences between output via parallel port ans output via a USB port.

Re:Printer format problems after moving 4.53DOS applications to LegEasy4DOS

The first problem is that the printer is not receiving the output as raw as the printer codes are interpreted as text. In RAW mode LegEasy4DOS will simply let the output pass-through without any interference so there is only two ways you can get this result:
1. It is not in RAW mode.
2. The wrong printer driver is selected for the workstation in DFD.

However as there is native support for Printers in text mode is very much abandoned and most "young" generations don't even know what it is LegEasy4DOS 1.0 support Epson MX/IBM Proprinter which it will format and transform to the correct Windows Format.

The best way to get a good result in L4D is simply to use EPSON MX-80 as the ONLY printer in the application and let L4D do the correct conversion.

By using RAW mode one will also be responsible for page formatting/page feed etc.

Re:Re:Printer format problems after moving 4.53DOS applications to LegEasy4DOS

The DataEase printer file for Epson MX-80 does not define a string to start using 12cpi. All my reports output a 12cpi printout to get more than 80 characters (96) along one print line. What string do I need to define 12cpi?  At present the reports appear to be 16 or 17.16 cpi.

Where can I get a list of formatting codes relating to Epson MX-80 ? Other printers have codes that are easier to determine how to set up a cpi setting for a new pitch.

Can't get back to edit my earlier comment.

I didn't quite follow the comment about "the wrong printer drive being selected for the workstation in DFD". That system is on a laptop running Windows XP and the driver has remained constant. Being 4.53DOS the whole of the procedures that have printed output have given it correctly for the last 20 years.

If the printer is actually in RAW mode then the output from 4.53 will be sent directly to the printer and no margins etc. will be added by LegEasy4DOS. The fact that you get print codes at the top and margins is evidence that it is not being printed in RAW mode.

It might be a bug in your version. Try to configure another print port for RAW and see if you get a different result.

LegEasy4DOS is emulation on all levels to allow you to run DFD in a x64 environment so it's not comparable to running this native in the past. The software take into account on all levels that the environment that existed when DFD was created is extinct and that goes from CPU/Memory/Networks and printers.

Our goal is to emulate all of these so the application can be run "as is" in a modern environment with modern printers.

Epson MX and HP Laserjet is supported by all modern printers for legacy purposes while their own native dialects has been abandoned so we need to standardise on what modern hardware support.

In DFD printer definitions codes need to be written in Hex.

So for 12CPI it is 1B4D.
