100% CPU when printing

If your printer is connected to your computer via a parallel port (or LPT), it can use 100% of your processor time for your prints. In some cases, other open programs do not meet longer during printing.
This issue is related to the parallel port which is connected to your printer. Windows does not support interrupts on the parallel port which leads him to use 100% of your CPU to your impressions.

The only workaround for this problem is to abandon the parallel port to connect your printer to your PC and instead use the USB port. We must make sure your printer supports this connection type.

how can i run tvs 240 dot matrix printer in lenovo laptop


This all depends on the printer server model you are using. You would need to provide the type of print server you are using. I have few of these lpt to usb and the problem is a lot of times it wont pickup the pc side the device. You would be better off getting a lpt to network they tend to work a 100 times better.

Have a Samsung desktop - how do I attach printer cable?


It really depends on the specific printer interface you have!

Newer printers can be attached to a Desktop or Notebook via the USB interface (small connector as for mouse).

Older printers, and 'commerciall' high speed printers, have a 'parallel' printer interface (large connector - LPT port) that will connect to a desktop (or higher end laptop) with a parallel (LPT) printer port. If you need a LPT connection, a USB to LPT converter can be used ... but a newer USB connected printer may be a cheaper alternative in this case!

Hope it helps let me know how you go.

sometimes when I'm printing, it will stop printing and show DATA PCL on the screen. I shut it off and back on and it prints garbage.....how can I fix this?? thank you


Try this if connected parallel:

This error may occur if you have a computer with an ECP port in Windows;
INCOMPATIBLE PARALLEL PORT PROTOCOL: During the PLUG n PLAY setup, Windows usually sets the parallel port driver for ECP mode if the computer's hardware port is set for ECP or, in some cases, ECP+EPP. Windows 95 will utilize data compression during ECP data transmission which can cause "garbled information" if the receiving device, such as a printer, is not ECP compatible.

SOLUTION:
Change the Windows Operating System's printer port driver (LPT.VXD) to the standard mode (non-ECP).
Windows XP:
1. Click on "Start", then "Control Panel.
2. Double click on "System:, and click on "Hardware", then click on "Device Manager"
3. Click on "Ports (COM & LPT)" section, and click on "ECP Port".
4. Click on "Driver", then "Update Driver"
5. Click "Install from List or Specific Location (Advanced)", click on "Next"
6. Select "Don't search - I will Choose Driver to Install", click "Next"
7. Select "Show Compatible Hardware"
8. Select "Standard Port" on the left window and "Printer Port" on the right window
9. Click on "Next" and Click on "Finish" and close all windows
10. Reboot/Restart your computer to ensure the changes are activated.

Dell 2330dn - my printer won't print my work. It keep reading Parallel busy. What does this mean?


How is this printer connected to your computer? Is it connected by a parallel/centronics cable, or USB, or perhaps not connected physically at all, but via network (it's a network-capable printer)?

Also, you don't specify the operating system.

I would guess, that it was installed on the LPT (parallel) port, instead of a network port, and because in reality nothing is connected to the parallel port it is producing an error (explaining why it's called busy would be long and boring).

Anyway, please either check the setting of the port to which this printer is printing (find that in Printer Properties), or be more specific as to what your current situation is.

You are correct on your deduction.
It is the USB to Parrallel adpter. They are not reliable in the XP/Vista enviroment. I have run into this several times.
