The configuration file controls the print driver settings and takes effect when the driver is installed. HP Driver Deployment Utility. DDU is used to pre-configure a print driver for deployment. When the package is run on the client computer, the new configuration file configures the printer driver after it is installed, and does not interfere ...
To determine whether a driver is Unidrv-based, the following steps need to be taken on Windows: Click the Start button, and then open the Printers folder. From the File menu, click Server Properties. Click the Drivers tab. Select a driver, and then click Properties. Observe the driver list in the Driver Properties dialog box.
In computers, a printer driver or a print processor is a piece of software on a computer that converts the data to be printed to a format that a printer can understand. The purpose of printer drivers is to allow applications to do printing without being aware of the technical details of each printer model.
A printing protocol is a protocol for communication between client devices (computers, mobile phones, tablets, etc.) and printers (or print servers).It allows clients to submit one or more print jobs to the printer or print server, and perform tasks such as querying the status of a printer, obtaining the status of print jobs, or cancelling individual print jobs.
A software-based virtual serial port presents one or more virtual serial port identifiers on a PC which other applications can see and interact with as if they were real hardware ports, but the data sent and received to these virtual devices is handled by software that manipulates the transmitted and received data to grant greater functionality.
If no printer port is present at 0x3BC, the second port in the row (0x378) becomes logical parallel port 1 and 0x278 becomes logical parallel port 2 for the BIOS. Sometimes, printer ports are jumpered to share an interrupt despite having their own IO addresses (i.e. only one can be used interrupt-driven at a time).
The "JetDirect" designation covers a range of models from the external 1 and 3 port parallel print servers known as the 300x and 500x, to the internal EIO print servers for use with HP printers. The JetDirect series also includes wireless print server (Bluetooth, 802.11b and g) models, as well as gigabit Ethernet and IPv6-compliant internal cards.
PLT (only in Hewlett-Packard's MS-DOS 2.11 for the HP Portable Plus [17] [18]) Returns no data. Sends data to the assigned plotter. The attached plotter device is reconfigurable.
