Lee Jones PCL intro and PCL command list

Based on http://itsa.ucsf.edu/~rpb/hppcl.html and information from http://www.csgnetwork.com/hppclhist.html with additional explanation and corrections by Lee Jones for <suppressed> project on 20 Sep 2004.

Hewlett-Packard Laser and DeskJet Printer Escape Code Sequences Collected and annotated by W.C. Parke, 1991. Edited and converted to html by R.P. Bagnall, 1996.

These Hewlett-Packard escape sequences are also known as HPPCL, HP Printer Command Language. This document reflects PCL 5 (the 5th revision to HP PCL command set).

HP provides 4 general types of commands to control the printer. They are single control characters, PCL escape sequences, HP-GL/2 vector graphics (not covered in this document), and PJL commands.

Single control characters

supported are:

<bs> backspace - move cursor one space to the left
<ht> horizontal tab - move cursor right to next tab stop
<lf> linefeed - move cursor to next print line (maintain current column)
<ff> formfeed - move to 1st line of next page (maintain current column)
<cr> carriage return - move cursor to the left margin of current line
<so> shift out - select secondary font to print subsequent characters
<si> shift in - select primary font to print subsequent characters
<esc> escape - beginning of an escape sequence (see below)
<sp> space - move cursor one space to the right

PCL Escape Sequences

always start with an ASCII Escape character, 1B hex, 27 decimal. The general format is extensible so that an older parser can recognize newer escape sequences and safely ignore them. There are two forms of PCL escape sequences:

Two Character Escape Sequences

have a second byte in range 48..126 decimal ( ASCII "0123456789:;<=>?@ABCDE...VWXYZ[\]^_`abcde...vwxyz{|}~" ).

Parameterized Escape Sequences

have a second byte in range 33..47 decimal ( ASCII "!\"#$%&'()*+,-./" ) then followed by a third byte "group code" in range 96..126 decimal ( ASCII "`abcde...vwxyz{|}~" ).

Parameterized escape sequences then have one or more single character action verb(s). Upper case and lower case characters have equivalent meaning as an action descriptor. Each action verb character triggers a specific function (see table below).

Each action verb may, optionally, be preceded by a numeric value field. The value field normally consists entirely of decimal digits range 48 to 57 decimal ( ASCII "0123456789" ). It may have a leading "+" or "-" sign character. If a decimal fraction is included, the field may contain one embedded decimal point character ( ASCII "." ). If the value field is not present, default of 0 is used.

The value field is normally represented by a # character in HP documentation and in the table below.

Parameterized escape sequences are terminated by the occurance of an upper case ASCII character, i.e. a byte in range 64..94 decimal ( ASCII "@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^" ).

Multiple parameterized escape sequences in the same group (i.e. which have the same second and third bytes) may be combined. First and intermediate action verbs are lower case (range 96..126 decimal). The final action verb must be upper case (range 64..94 decimal).

For example, to set the horizontal margins to columns 4 and 76, the following can be used:

<esc>&a4L

<esc>&a76M

They can be combined into a single sequence of:

<esc>&a4l76M (where l is lower case el character)

Here's another example of equivalent commands. To move the cursor to row 13 column 25, use one of the following:

<esc>&a13R

<esc>&a25C

or:

<esc>&a13r25C

or:

<esc>&a25c13R

Some parameterized escape sequences are followed by a counted number of arbitrary data octets. The {data} field follows the terminating action verb. Length of {data} is specified in the value field. The content of the {data} field is ignored (i.e. not interpreted as PCL commands).

Okidata printer configuration appears to be ASCII commands bracketed between special lead-in and trailer sequences. Note that they adhere to the general format of HP PCL parameterized escape sequences.

<esc>%-12345X@PJL lead-in for Okidata printer configuration

<esc>%-12345X trailer after Okidata printer configuration

Turns out that the <esc>%-12345X is defined by HP as part of PJL (Printer Job Language). It provides control of per-job elements and allows setting printer configuration (either defaults using the DEFAULT keyword or immediate change using the SET keyword).

<esc>%-12345X is the Universal Exit Language (UEL) command. It is immediately followed by @PJL (no intervening characters) then a single PJL command or a linefeed to enter multi-line PJL mode.Each line in multi-line mode must begin with the @PJL<sp> string.

Okidata supports standard HP commands to set common variables.They seem to have extended it with additional Okidata-specific variables that have an OKI prefix.

Hi Lee,
Your page contains the most info I have been able to find regarding secondary font commands, including HP sites, that I have purused. Thank you!
Even though, I am still searching for a method to fix a problem. Maybe you can help.

I have an erp system that print to pcl5e capable printers. We use only HP printers. Let me tell you what happens and how they do things...

Each printer has a "barcodes and more" dimm installed in it. To get barcodes to print from the erp system, we go into the printer configuration, and under pcl, select the dimm slot and the appropriate barcode font to print. (slot 4, id 16)
The erp system sends text as usual, up to the point it wants to print a barcode. Then it sends an escSO (chr(27)chr(14)), followed by the text to be barcoded, followed by an escSI (chr(27)chr(15)). The barcodes print as advertised. Apparently selecting the pcl font source and font id thru the front panel tells the printer that this font is the 'secondary' font. When the escSO command is sent, it shifts to this secondary font, prints the text using the secondary font, then shifts back to the primary. So far, so good.

Now we have a downloadable barcode font. We download the font to the printer, and give it a font ID of 18. It appears in the pcl font listing as a HP PCL5e Permanent Soft Font, Font # SOFT 4, Font ID 18. In testing we send the command esc)18X, which is supposed to tell the printer that font 18 is the secondary font. Then we send and escSO, followed by some text to print as a barcode, then an escSI to shift back to the primary font. What appears to happen is that the text prints using the 'internal' font 18, instead of the soft font 18.
I have tried using various combinations of esc)18X and esc)18@, but am getting nowhere. Maybe there is a command that tells the printer to use a "soft font" rather than an "Internal" font.
If you have a chance, and this is something you have knowledge about, please let me know what you know.
Thanx very much in advance.

James Newton of Massmind replies: I would recommend selecting the font via the font selection string as listed on the PCL typeface list. That removes any issues with the source of the font and works reliably in my experience.+
