AutoCAD LT supports PostScript printers and plotters using either a Centronics-type parallel I/O port or an RS-232C serial I/O port. If you use a serial port, it is recommended that you set the printer for 9600 baud, even parity, 7 data bits, 1 stop bit, and XON/XOFF protocol (some have a choice of XON/ XOFF or DTR). If your printer requires a different configuration, enter yes at the Do You Wish to Change the Serial Port prompt, and enter the correct values for your device.
AutoCAD LT produces output at 300, 600, 1270, or 2540 dpi. Select the AutoCAD LT output resolution that is closest to the resolution of your laser printer. Although output produced by AutoCAD LT at any resolution prints correctly on any printer, plotting takes longer if you choose a higher resolution than your device supports.
To ensure that the plot appears on an area of the paper that can accept an image, AutoCAD LT offsets the X and Y values by 5/18 inch. If necessary, you can change this origin at the time of plotting to any negative or positive origin offset. On a standard plotter, choose Rotate so that the longer dimension of your image is oriented with the longer edge of the paper (landscape format).
The PostScript printer driver supports plots containing up to 255 colors. It is suggested that you plot chroma.dwg to see the colors assigned to the AutoCAD LT colors. Chroma.dwg contains a grid of color swatches representing the 255 AutoCAD LT colors. Use the output to customize your color needs. Assign the pen number that most closely fits your desired color to the AutoCAD LT color and layer.
During configuration, the following end-of-file prompts are displayed. To configure your PostScript printer, respond to each prompt.
Some PostScript devices require a special ^Z character at the end of the file. Do you wish to append ^Z?
Adobe recommends that a special ^D be added at the end of the file if the Adobe Standard Protocol is used. Do you wish to append ^D?
If you are sending a PostScript file over a communication channel that uses Adobe Standard Protocol, append a ^D to the end of file. If you are porting to another platform, you might want to remove this character; otherwise, you receive an error message when printing the file.
If you are plotting to a network PostScript printer, or if you are plotting to a locally connected PostScript printer through the Windows system spooler because of a conflict with a Windows system printer driver, you will probably need to append a ^D to your file to avoid a time-out error.
If you have a roll-fed plotter with level 2 PostScript, you may want to limit the paper used to the selected AutoCAD LT paper size. Do you wish to limit the paper size?
If you have a roll-fed PostScript device, such as a Hewlett-Packard DesignJet 650C and are not setting the paper size at the control panel, select this option. If you do not limit the paper size, the paper size will not match the size that is required for the plot.
