Q. When in PostScript mode, the printer will not print a page. if I send it an

ASCII text file or do a "PrintScreen". Why?

A. The PostScript interpreter, which process the information sent to the

printer, only recognizes PostScript operators (instructions). Since an

ASCII text file or a "PrintScreen" usually do not contain PostScript

operators in the proper order, the printer will not output the page. In order

for a PostScript printer to properly output a page, the file sent to the

printer must contain proper PostScript operators such as; which font to

use and where to position the text on the page.

The recommend method to output an ASCII text file is to import the file

into a word processor application program and then print the file from

within the application program. The application program will format the

ASCII text file into proper PostScript operators before sending the file to

the printer. The recommended method to perform a "PrintScreen" is to

set the EPL-7500 to HP emulation mode prior to sending the PrintScreen.

Q. What is an easy way to verify that the EPL-7500 printer is communicating

with an IBM PC or compatible computer using LPT1 from the DOS prompt

with no special software?

A. The easiest way to test the EPL-7500 from the DOS prompt is to use

DOS' COPY command to send the EPL-7500 the PostScript operand to

eject a blank page. If the computer and EPL-7500 printer are

communicating properly and the printer is set to PostScript mode, the

following sequence will cause the EPL-7500 printer to eject a blank page:

COPY CON LPT1: [ENTER]

showpage [CTRL]D [CTRL]Z [ENTER]
