[Bug 11917] New: Parallel port printing problem (missing flow control?)

http://bugs.winehq.org/show_bug.cgi?id=11917

Summary: Parallel port printing problem (missing flow control?)
           Product: Wine
           Version: unspecified
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

http://www.winehq.org/pipermail/wine-users/2008-March/029601.html
and
http://www.winehq.org/pipermail/wine-users/2008-March/029648.html
say that printing directly to a dot-matrix printer
by writing directly to LPT1 works if you write one
byte at a time, but fails with missing chars if you
write many bytes at a time.

User gave a nice test program to illustrate the problem:

program timp; (* Delphi 7 *)
{$APPTYPE CONSOLE}
uses
 SysUtils,windows;
(* Star SP200 Buffer off sw 6 on, Epson TM-U210PD buffer off sw 1-2 on*)
var
 devname : string = 'LPT1';
 ps : array [0..41] of char = '0123456789012345678901234567890123456789'#10#13;
 nl : array [0..3] of char = #10#13#10#13;
 i,i2,FHandle : integer;
 e : DWORD;
begin
 FHandle := CreateFile(PChar(devname), GENERIC_WRITE, 0, nil,
OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL, 0 );
 try
   for i := 0 to 49 do
     WriteFile(FHandle,ps[0],42,e,nil); (* xp ok *)

for i := 0 to 3 do WriteFile(FHandle,nl[i],1,e,nil);

for i := 0 to 49 do
     for i2 := 0 to 41 do
       WriteFile(FHandle,ps[i2],1,e,nil); (* xp&wine ok *)
 finally
   CloseHandle(FHandle);
 end;
end.

exe: http://ajuda.variavel.com/timp.zip  (I'll attach it)

Wine version 0.9.28 kernel 2.6.21, large printer buffers can hide the problem.

Very old version of wine.  I'll ask him to update.

Looks like a flow control problem.  User writes:

[Problem doesn't show up with large hardware buffer in the printer.]
A larger buffer than the job may not show problems.
In a POS printing a invoice is a small job 1K-2K, a older printer with a small
buffer (Star SP200 1K buffer)
 will see problems a newer printer with a large buffer (epson TM-U220 4K)
 seems to work must of the time, so to test I disable the hardware buffer,
i tried do change the bios settings (normal, epp etc) and the parport options
(irq=none, dma=none etc) to no avail,
and the problem shows even in a vmware guest.
