PQ-8P, PQ-8S

Table 5-7. Summary List of Special Commands.

 

 

Command

Function

 

 

¬E

Sends an ASCII ESC command to the printer

 

 

¬TY

Enables true 6 LPI printing

 

 

¬TN

Disables True 6 LPI printing

 

 

¬I

Ignores all host formatting commands

 

 

¬S

Stop ignoring host formatting commands

 

 

The ¬E command allows an “Esc” command to be sent to the printer to control the printing. Simple “escape” commands eliminate the need for putting in hex codes using Command Pass-Thru. These commands allow use of some of the special features of the laser printer.

Check the printer’s manual or any optional technical manual for a description of the feature and the escape commands needed to access the feature. These commands consist of characters which are all found on the IBM twinax keyboard except for the Escape character. For example, ¬E(s3B would begin bold printing on an HP LaserJet printer.

The printer will slightly compress line spacing to fit 66 lines onto the page. This may be undesirable (as when you are using pre-printed forms that must align correctly).

In these cases, the ¬TY command prevents the printer from compressing the line spacing.

Use the ¬I and ¬S commands to remove unwanted host commands from a print file. For example, when printing with electronic forms software, these files are recognized by the host as text files, which causes the host to format the files with unwanted carriage returns and line feeds. Placing the ¬I at the end of a line and ¬S at the front of the next line causes the PQ-8 to remove the host carriage-return and line-feed commands and send only the data to the printer.

I-O’s laser printer emulation is compatible with the many popular electronic forms software applications. If the PQ-8 replaces XPoint’s Twinax Controller, set the PQ-8’s True LPI menu to “XPoint Controller.”
