I had the same problem, i.e. slow startup and copying takes a second or two. I did locate a network printer causing the error. Hence, the following worked for me, which switches the default printer to one that is local, like Acrobat Distiller or the AdopePS:

8. Make Sure Your Printer Driver is Compatible With Illustrator
Specify a PostScript printer as your default printer to determine whether there is a conflict with current default printer driver:
1. Choose Start > Settings > Printers.
2. Right-click a PostScript printer (other than the current default printer), then choose Set as Default from the pop-up menu. Do not specify a non-printing output device, such as a fax or modem. If a PostScript printer driver isn't installed, install the AdobePS 5.1.2 driver from the Illustrator application CD, or download it from Adobe's Web site at
To determine which driver a printer is using:
1. Right-click the printer icon and choose Properties from the pop-up menu.
2. Click the Device Settings tab.
3. Select the printer name at the top of the list and click About <Driver name>.
4. If the About dialog box includes the word "PostScript" (e.g., "Adobe PostScript Printer Driver"

the printer is using a PostScript driver.
