Abstract: The user defined functions for the LQP78 enables OS/8 BASIC

to control the printer like an X-Y plotter. The LQP78 is normally used as a

letter quality printer. It also has the capability of moving the carriage right

or left in 1/120 inch increments and moving paper up or down in 1/48

inch increments. Therefore, from a machine language level the LQP78 can

be controlled like X-Y plotter with acceptable resolution for many

applications.

Restrictions: May use some characters of the LQP78 printer extensively

thereby shortening the life of the print wheel. Care should be taken ini

assigning values to the character position as it is possible to drive the

carriage against the right-hand carriage stop which may cause printer

damage.
