Direct Printing to LPT1 is slow
Hi everybody...
I've a Dell Optiplex GX1 with Windows 98SE, 64MB Ram. I've developed a program that writes data directly to the LPT1 Port, bypassing the installing printers on the system. On other computers with Windows 98SE, it works fine. With the computer described above, from Windows it prints, but when the program try to print to LPT1 Port, the task is done but in "slow motion", one line at a time. This computer was working with the program for at least 2 years and reports no problems like this. I've already reinstalled Windows 98 to no avail. I've already check disk fragmentation, port conflicts, reinstalled printer drivers (I did it with some hope to solve this problem), also copied again the lpt.vxd directly from the CD (with the extract utility). Also done a Windows Update and nothing... The problem is only reported when printing from any program that prints directly to the LPT1 Port. An example of what looks alike my routine: port = fileopen("lpt1") //Open the ports and wait for data filewrite(port, 'some text here') filewrite(port, 'some text here') filewrite(port, 'some text here') filewrite(port, 'some text here') filewrite(port, 'some text here') fileclose(port) //End the printjob Please help is needed ASAP.. This computer is used in the payroll department, and is used to print payments by check.

Let me check on PORTMON.... and on Bios, i've already change the configuration TO ecp, epp, spp, and still the same... I also thought it was a printer problem, but using the same printer on another computer is doing the same thing is ok... Also change the interface cable between the lpt1 port and the printer (the printer cable) and still nothing... using the same cable with other computer/printer works....

What happens if you try to print something from a DOS shell?
Like "dir prn" or "copy [sometextfile] prn" Is it sluggish? If it is, try booting directly into DOS and try it. No solution I realize, but might help troubleshooting a bit.

But I don't see any data written to the port. I was thinking, W98 has a printing feature which maybe causes this problem, but I don't know the English word for it. When you go to the 'Printers' page in control panel, rightclick the printer, choose properties-tab details. Then a button 'wait queue settings' or something like that. Try different settings here. When this doesn't work, I suggest a workaround. When you write to an ordinairy file, you can reboot to dos and copy the file to the printerport.

Hi everyone...
from the DOS Shell doing what Mr. Hershberger wrote, it prints slow, from any DOS application that needs to print directly to the LPT1 port it prints slow.. I've check this also on my own computer, that reports the same computer, and the only difference between them is that in mine i do a clean install on my computer and everything works fine.... The other computer I'm troubleshooting , i can't do a clean install on it, because it has too much sensitive data ( if u know what i mean ...  )...As Mr. Haggis says, in the output file i send from portmon utility, that's the only piece of code i got, because the printer hungs up in the middle of printing... it opens the port, send some info and when it supposed to start printing, with portmon it hungs up.... if i do it normally, it starts printing at a slow rate....
