Computer Hardware Registry Modification Example (ii) _ Registry

In Windows XP, you are allowed to use registry modifications to set up your printer:

To enable the printer alert sound:

When a remote print job returns a message with a print server error, Windows XP allows the Beep alert user to be enabled every time the job is retried (once every 10 seconds). To enable Beep events, open the Hkey_local_machinesystemcurrentcontrolsetcontrolprint subkey branch in the registry, and change the value of the key value item "Beepenabled" in the right window to 1.
To disable a printer's browser thread:
There is a "Browser" feature in Windows XP that you can use to advertise existing resources on your computer to other computers on your network. If you want to disable this feature, open the Registry Hkey_local_machinesystemcurrentcontrolsetcontrolprint Branch and change the value of "DisableServerThread" in the right window to 1. If you do not have the key value item, you can build it yourself.

Reduce data throughput in fast printing:

A feature of Windows XP when you print quickly, which allows you to send a print job to a printer when it is created by an application. In some cases, this can result in too much data being sent to the printer, which allows us to reduce the throughput of the data by setting up the registry. Opens the Hkey_local_machinesystem current Controlsetcontrolprint subkey branch, and "Fastprintslowdownthreshold" the key value entry in the right window To a smaller value (the unit is MS).

To speed up printing:

Quick print allows the printer to be sent to the printer when the print job is being created by the application, and if the application is paused while the data is being sent, it is closed back. In order to correct this error, we can modify the registration form. Opens the Hkey_local_machinesystem current Controlsetcontrolprint subkey branch, and "Fastprintthrottletimeout" the key value entry in the right window is changed to a smaller number (the slowest speed is one byte per frame).

To set the quick Print timeout value:

Opens the Hkey_local_machinesystemcurrentcontrolsetcontrolprint subkey, changing the key value of the key value item "Fastprintwaittimeout" in the right window to a larger value. To accommodate slower applications.

To set the decay time for a printer queue:

On a busy LAN, which printer is constantly changing for printing at a certain time, we can refresh the available printers on the LAN to make it easier to see the printers that are available instantly. Open the HKEY_LOCAL_MACHINE SYSTEM Currentcontrolsetcontrolprint subkey and change the value of the key value item "Netprinterdecayperiod" in the right window to a smaller value. The list of printers in the Browse dialog box is more frequent. The refresh is based on the situation on the network. But here's one thing to note: The key value is in MS, which is milliseconds, and if you mistakenly set it too small, the network stops because of a constant refresh request.

To control the priority of the printer port thread:

Each printer port has one or more threads responsible for sending data to the physical printer. You can control the priority of the threads here by modifying the Windows XP registry. Open the Hkey_local_machinesystemcurrentcontrolsetcontrolprint branch and modify the values in "Portthreadpriority" in the right window to the value you want. where 0 represents "normal thread priority", 1 means "higher than normal thread priority" and full F indicates "lower than normal thread priority".

Control whether printer errors are displayed on the remote computer:

Opens the HKEY_LOCAL_MACHINE SYSTEM current Controlsetcontrolprintprovider [Printservicename] sub-key branch, where [Printservicename] A print vendor in quotation marks, adding a Double-byte key value item data in the right window, named "Netpopup", setting its value to 1 to indicate that it pops up a dialog box with a remote error, or, if set to 0, disables the feature.

To enable trusted printing:
To prevent unauthorized printer servers from acquiring resource controls on a confidential printer, you may want all print jobs to come from a trusted windows.net server. To do this, you can modify in the registry: Open the Hkey_local_machinesystemcurrent controlsetcontrolprintprovider lanmanprintservices subkey Branch, Change the value of the key item "Loadtrusteddrives" in the right window to 1.

All of the above operations, if the original registry does not have the key value entries, can be established.
