• Toner Level

o A single digit return giving a rough estimate of toner remaining

o 9 = Full, 0 = Empty

• Cartridge Count = xxxx

o Data indicating toner usage by counting pixels printed

• Low Threshold = xxxx

o The Toner Low point based on cartridge count value

• Empty Threshold = xxxx

o A cartridge count value that determines when printing must stop to ensure

quality MICR documents

PJL MICR Command Example

Figure 8.1, is an illustration of an Accounts Payable check and remittance information.

The page used a PCL macro for the static data and background design. This manual

does not address macro design and programming, but the variable text information

including all the PJL and PCL commands used to print the example are on the page

following the sample check. For illustrative purposes there are some extra spaces in the

text preceding the printable data. The following paragraphs describe the command

functions. The commands are a minimal set chosen to produce the example. Please

consult Lexmark Technical publications for the complete descriptions of PJL and PCL

printer commands.

PJL Unlock Sequence

The first two lines of the variable text example are PJL commands that unlock the MICR

font resources and enter PCL language processing. The password used is PASSWORD,

the initial ship default. These commands and all following commands are all case

sensitive.

<ESC> is used to illustrate the ASCII Escape Character, ASCII 27, hex 1B. An actual

data

stream requires the Escape Character, not <ESC>.

PCL Initial Set-Up

The next two commands set up some printer PCL variables. These commands are

normally early in the data stream. We chose a minimal set. <ESC>&l2a1h6d1e64F sets

the paper size to LETTER, the input tray to TRAY 1, the lines per inch to 6, the top

margin to 1, and the lines per page to 64. The next command, <ESC>&u600D, is the

Unit of Measure command set to 600 dots per inch mentioned in Section 7. This affects

proper MICR line spacing and X and Y cursor positioning.

PCL Macro Call

The next command calls macro 100 that was previously loaded in RAM memory. When

called, the graphic background, logos, and static data are written to the internal print

buffer.

PCL Font Calls, Positioning Commands and Variable Print Data

The next eleven lines of data in the example call printer resident fonts, position the

cursor, and print the variable information. This is using the minimal data required,

particularly the font selection strings, <ESC>(s4099t0b10H being a very short version to

call Courier, normal weight, 10 pitch.
