Default Re: Dot Matrix printer progressively misaligns when printing forms

If you go far enough into the install new hardware process, under printers,
you should find "Generic", "Generic Text Printer".as a driver choice. This
driver may or may not be compatable with your application. It can sometimes
also be used to print to a file instead of the printer, and produce a
readable (in Notepad) file. This may help is determining why the printing
shifts on the forms.

Even though you are inputting text information it may be printed as a
graphic image on a printer. (RAW mode) The dot matrix printers generally
had both ASCII character print capability and graphics (raw) mode printing.
These days, windows ink & bubble jet printers generally operate in a
graphics modes only. A complication has to do with use of built-in vs.
downloadable printer fonts on the dot matrix printers. I have an Epson
printer that can use both (The last dot matrix printer I bought.) It worked
ok with win 3.1, and started having odd problems with later windows
versions. (Turned out that the printer's hardware buffer was not large
enough to buffer data that corresponded to a complete line of text.) Since
the printer was bi-directional, this might result in a "damaged" printed
character in the printed line. Since it was painfully slow in comparison to
even the early bubblejet printers, it was retired.

One of the things to look for on sprocket feed forms is a periodic variation
between forms. We used to see this when the backing paper was perf'ed across
at around 11", and there were multiple labels/forms between each perf. (You
set the form length to the distance between these perfs.)
Another issue was that some of the printers had a "skip over perf" feature
that seemed to screw up the driver's line count. This is part of a set of
forms control functions that were referred to as a "VFU" on mainframe
printers. If the internal printer "VFU" functions are enabled, they may
conflict with the windows drivers.

Another gotcha had to do with setting how the printer responded to form
feeds and line feeds with or without a C/R. There used to be switches or
control panel settings on the printers.

An old "trick" in setting up dot matrix printers was to generate a text file
with a text editor (notepad) That had a number or character in the first
and last character positions that corresponded to the width of the form.
This was repeated until the number of line was enough to span more than on
or two forms, or pages of forms if needed.

The text file was then copied to LPT1: via the copy command with a binary
option. This generally shows if such things as skip over perf are active, or
other strangeness is occurring.
